Video Game Mechanics: A Beginner’s Guide (with Examples)
Video Game Mechanics: A Beginner’s Guide (with Examples)
Mechanics are at the heart of gameplay design, and yet the concept is widely misinterpreted.
I’ve had game directors with 10+ years of experience misuse the term. On the other hand, I’ve met junior designers who understand the concepts naturally without knowing the industry terms.
Whatever your experience level, a thorough understanding of the nature of game mechanics is essential for crafting rich game experiences. Without it, you’ll be stuck reusing the core mechanics of other games.
And while recreating Mario’s jump is a good starting point for beginners, at some point you’ll likely want to create your own core gameplay loop. And to prepare yourself for making more novel and advanced games, you’ll need a foundational understanding of game mechanics.
What Are Video Game Mechanics?
You can find long, scholarly takes on this question, but I’d rather cut to the chase.
Game mechanics are the interlocking pieces of the game that can interact with each other in a meaningful way. It doesn’t matter if you’re designing a roleplaying game (RPG), a first-person shooter (FPS) or an action adventure game. There are parts of the game that have meaningful consequences, and parts that are fluff.
Mechanics are the bits with consequence. The exact same thing can be a mechanic in one game and fluff in another. If you fire a flaming arrow in one game, and it burns away a patch of vines revealing a path, it’s a mechanic; it can meaningfully affect the game world.
In another game, the exact same concept, a flaming arrow, might trigger an amazing VFX of burning grass, but otherwise act just like a normal arrow. In that case, the fire is fluff; it has no meaningful effect on gameplay.
I’ll get into the many different kinds of mechanics soon, but in general, a good sign of a strong mechanic is one that interacts with a wide variety of different situations or shapes how you play the entire game.
‘Fluff’ in Disguise
Don’t get me wrong, there’s a place for fluff (I love an impactful visual effect), but a mechanics designer needs to see through the illusion.
Jumping might be the core mechanic in Super Mario games, but in a game where jumping makes little to no difference, it’s fluff.
The ability to stare down the sights of your gun is another example of fluff, unless doing so improves your aim or slows your movement.
One of my favorite examples of a mechanic is spell interruption, a design tool I used regularly for both World of Warcraft and League of Legends. Whether it’s a Rogue’s melee Kick, Soraka’s AoE Equinox, or Yasuo’s launching whirlwind, this mechanic interacts with a ton of different opportunities created by the designers throughout the game.
Yasuo’s Steel Tempest is one of many interrupts in League of Leagends, but its trajectory and cast conditions give it its own mechanical feel. (Image from Steemit)
Mastering this mechanic as a player means learning when it’s a useful tool, then refining your timing in each scenario. Mastering this mechanic as a designer means providing enough opportunities for play and counter-play, as well as clear game rules to keep its behavior consistent.
Examples Of Video Game Mechanics
- Jump in Super Mario
- Shield in Halo
- Skydiving and the storm in Fortnite
- Rotate in Tetris
- Weapon power-ups in Doom
- The portal gun in Portal
- Block placement in Minecraft
- Steering and power-ups in Mario Kart
Things that are not game mechanics:
The last section will probably spark a defensive reaction in some of you. That’s okay, just set your resistance aside for now. There’s a method to this madness.
On their own, money, tokens, art, and so on, are not game mechanics. However, they can be representations of game mechanics. The actual mechanic is the action tied to the object—what actually happens in the game.
All of these bolded actions are game mechanics:
- Spending money
- Awarding a token to represent your score
- Timing your actions with the help of animations
- Pressing a button to change the game state
- Informing the player with sounds, visual art, or cinematics
Notice there’s no action listed for dice. Rolling dice is not a mechanic, even though it’s very often confused for one. Dice are just an expression of uncertainty. Rolling dice (or flipping a coin or randomly generating a number) just adds variance to the result of a mechanic.
Think of dice as random number generators: useful tools, but not game mechanics.
If you’re confused, just remember this:
Mechanics connect game elements to produce outcomes. The device used to scramble that outcome is not the mechanic itself.
Sidebar: Decks of Cards
Drawing and playing cards, on the other hand, can be game mechanics, since they change the game state. A card drawn from the deck gives you new ways to interact with the game, and, since it is no longer in the deck, changes the probabilities of future actions as well.
(And yes, there are atypical games that turn dice rolling into a mechanic. For instance, a limited pool of varied dice is similar to a deck of cards.)
The Difference Between Game Mechanic and Gameplay
These terms get thrown around so often the difference between them can get blurred to death. However, just as individual music notes are not a song, game mechanics are not gameplay.
And just as a sequence of beautifully arranged notes can flow together into a song, a well-designed sequence of game mechanics can create smooth, satisfying gameplay.
Or if you prefer it without the metaphor: Gameplay is the flow between challenges, mechanics and outcomes.
Designers often analyze this flow by looking at gameplay loops: sequences of actions and events repeated by the player. Good game mechanics make the loop smooth and satisfying, while flawed mechanics can undermine it.
Stomping on a koopa, kicking its shell to defeat another enemy, then jumping again to dodge the ricochet is gameplay. The small atomic pieces of jump, stomp, kick and jump again are mechanical elements that combine to create a gameplay loop you’ll experience many times.
Questing is an example of a longer gameplay loop, composed of quest discovery, travel, objective completion and reward collection. The player actions along that journey can involve many different mechanics, from stealthing to combat moves to multiplayer interactions.
These loops are incredibly important. The design decisions about which mechanics are front and center in a game often define the game’s genre and audience. If a mechanic doesn’t fit into a gameplay loop, it won’t have many chances to shine.
Core, Primary and Secondary Mechanics
Game development is ultimately always about choices. Most successful games carefully focus on a core mechanic and design gameplay loops that challenge the player’s mastery of it.
Additional mechanics are there to support the core game mechanic, not to create an “all in one” game where anything is possible but nothing feels connected.
For this reason, we separate mechanics into three buckets: core mechanics, primary mechanics and secondary mechanics.
Attacking is a core mechanic in Smash Bros.; without it, it’s not even the same game. (Image adapted from The Game Crater.)
Your core game mechanic is the foundation of your game. Mario has jumping. Call of Duty has point-and-click gunplay. Hearthstone has playing cards from a deck of cards. This provides the foundation and ideally supports the emotional drive of your game.
Primary mechanics fall in line to support this. Mario has wall-sliding. Call of Duty has weapon reloading. Hearthstone lets you attack with minion cards. These primary mechanics lean heavily into supporting the game’s core mechanic.
Secondary mechanics add depth, flavor and variety. Fire flowers, grenades, and Taunt minions are all great examples. The game would still work just fine without them, but their addition adds new experiences and allows for new challenges.
Be careful: more is not always better. Carefully introduce new mechanics through gameplay or tutorials.
Varying the Core Mechanic
The core mechanic is the bedrock of a game, but it is often expressed in several ways.
In Portal, you start by interacting with existing portals, then get a portal gun that links to an existing portal, then upgrade to making all portals yourself. These are three ways of playing with the core portal mechanic.
On top of this, your portal use is supported or challenged by many other mechanics, adding variety.
Secondary mechanics, on the other hand, are usually limited to a simple form and lack support from other mechanics.
For example, the portals in Darksiders only connect predefined locations. The game is not about portals, so adding new uses for portals would risk distracting from the core gameplay.
Goals and Gameplay in Different Game Genres
Almost any game you make will fall into one genre or another, or occasionally slip into an intersection between a couple genres. In order to meet audience expectations (or break them in a useful, intentional way), you’ll need to be familiar with the genre’s core gameplay experiences.
RPGs: Role-playing games
Whether it’s a turn-based game like Final Fantasy, real time combat like Dark Souls, or a point-and-click Diablo-like, RPGs consistently include certain elements.
Because RPGs are first and foremost about a sense of growth, progression and overcoming adversity through persistence, these games typically share and reuse the same concepts over and over again:
- Power growth
- Experience / character level / stats increase over time
- Gaining abilities adds power and versatility
- Failure tolerance
- Generous respawn mechanics
- Equipment system
- New items
- More equippable slots
- Better access to consumables
FPSs: First-person shooters
First-person shooters universally center around aim-and-click mechanics. They can be open world games, or use the “shoebox & corridor” style of heavily controlled level design.
Because FPSs are focused around aiming, timing, positioning and ammo management, they often have a higher focus on individual dexterity, reaction speed and physical endurance. (I personally struggle with these types of games due to a lifelong struggle with jittery hands.)
- Aim, bullet trajectory, spray patterns
- Variety of guns (shotguns, snipers with sights, and so on)
- Respawn mechanic typically harsher than RPGs
- Timed respawn (Deathmatch)
- Wave respawn (CTF / Capture the Hill)
- Permadeath (Battle Royales)
- Weapons, health packs, tossables
- Body armor, ammo, shields
Board games span an immensely diverse space—from Go to Gloomhaven—so putting them into a single category seems almost reckless. However, while you could definitely go deeper by analyzing a specific subgenre, there are still common features that board gamers expect:
- Measurable victory conditions
- Victory points or win/lose conditions
- Catchup mechanics to allow the lead to change hands
- Resources & resource engines
- Resource generation over time
- Resources have variable price or usefulness
- Unlocking new ways to gain resources
- Rule creation & rule breaking
- Gaining new gameplay options (deck-building, passive powers)
- Counterplay (traps, targeted interactions, setting new rules)
- Deception and persuasion
Including everything from racing games to farming simulators, simulation games give you a taste of a new lifestyle. Through dramatically simplified mechanics that mirror the emotional experience of the original activity, these games allow you to safely experiment with alternative fantasies.
This is another diverse genre, but we can still identify some core components:
- Self-directed exploration & ways to express yourself
- Systematic trial-and-error experimentation
- Intrinsic goal-setting opportunities
- Improvement through learning
- Iterating the same gameplay loop
- Refining your process for greater results
- Scoring and reward systems layer atop core gameplay
Context: Getting the Most from Mechanics
It’s not enough to just build a new mechanic. If the mechanic doesn’t have enough chances to have a meaningful, memorable impact, it’s often better to cut it entirely. As a designer, you need to create the context that lets your mechanics shine.
I’m reminded of the Cane of Somaria from The Legend of Zelda: A Link to the Past, an item that creates blocks to hold down switches or fill pits.
This is a great idea on its own, but it’s only available late in the game, and is only useful in a few situations.
As a result, it’s much less memorable than items like the Hookshot.
To avoid this situation, scatter different challenges throughout the game with your mechanic in mind. Then, when a player gets access to a new mechanic, they can revisit older content to find new, more powerful ways to overcome old objectives.
For instance, in one game I’m currently working on, enemies with shields are initially frustrating and difficult to overcome. Once the player gains the ability to destroy those shields, these experiences are much easier, reinforcing the sense of power progression core to RPGs.
Generally speaking, there are three types of context that can help maximize your mechanics. Here’s a questionnaire to help guide your thought process as you design for each one:
- How does this mechanic change how I interact with enemies?
- How do enemies disrupt my ability to use this mechanic?
- Is this mechanic useful frequently, but not constantly?
- How does this mechanic change my relationship with friendly units or players?
- Does this new mechanic reward observation, coordination and creativity?
- How does the world respond to this mechanic?
- What doesn’t react to this mechanic and why? Is it well communicated?
- Can I enable or disable this mechanic at different points to vary the challenges?
These aren’t either/or options. If your mechanic can destroy both enemy shields and locked doors, it has even more opportunities to make an impact.
Video Game Mechanic Mistakes To Avoid
Your journey into the universe of game mechanics will not be easy. You’re going to experiment, make a lot of mistakes and throw away a lot of work in the process. That’s okay. But hopefully I can help you avoid some of the most common offenders.
Mistake #1: Contextualization Is Not the Mechanic
A sword, a flaming sword, a lightning sword and a lightsaber are not separate mechanics. At the end of the day, these are just different damage numbers at the end of an attack mechanic. (Just ask a Star Wars fan whether “hit for 2d8 damage” lives up to the Jedi fantasy.)
Even making some enemies weak to fire and some weak to lightning does not make the flaming and lightning swords different mechanics. In that case, the mechanic is type weakness—a concept that Pokémon built the majority of its genre around.
Now, if you allow flaming swords to ignite vampires and lightning swords to send electrical arcs to nearby secondary targets, you’re on the right path. Creating these differences in gameplay and supporting them with enough relevant opportunities is at the heart of mechanics design.
Mistake #2: Tutorialization Is Not Rich Gameplay
Trapped behind a thick vine barrier, the player cannot leave until they set a torch alight at a fireplace and carry it to the vines to burn a pathway.
Fighting a duelist who deflects every blow, the player cannot win unless they disarm their opponent first.
Both of these scenarios would make great tutorials, introducing a major game mechanic and forcing the player to internalize it.
However, repeatedly dropping these exact scenarios throughout the game creates a frustrating gameplay loop where the player never has the opportunity to grow or innovate. To provide a satisfying player experience, a mechanic can’t be the same every time.
Even a straightforward attack mechanic can be engaging with enough alternatives and a variety of enemies.
Instead, vary the challenge with new complications, or give the player new ways to overcome the obstacle. If the next courtyard introduces wind that blows out their torch, the player needs to find a new solution—like the fire spell they’ve just learned.
This kind of internal growth and creativity is essential for long-term engagement and a sense of power.
Mistake #3: Throughput Is Not a Mechanic
A fast saber slashes the enemy, slicing them for four damage. A heavy two-handed great hammer crushes the enemy for eight damage.
Both cost one action. Congrats, you’ve discovered one of my major pet peeves about combat in Dungeons & Dragons.
These weapons have different throughput: they deal damage at different rates. But since they have only one, identical mechanic (attacking for damage), there’s no reason not to just pick the most powerful weapon your character can wield and attack every turn.
And sure, tuning the throughput is important for game balance.
If sabers only deal four damage but can slice twice per action, the incentives are more even and players will use a wider variety of weapons. But you still aren’t designing game mechanics!
Approaching the problem from a mechanics design perspective lets you accomplish so much more. Give weapons different abilities, characteristics, and ways of interacting with the world, and you’ve given players a rich, narratively satisfying set of combat decisions.
Example 1: when we made Ori and the Will of the Wisps, we tuned the throughput, but we didn’t stop there. Hammers are slower and hit harder than swords, but they also push enemies farther back and shatter shields. These mechanical differences are what make each weapon unique.
Example 2: The Dark Souls series also leans heavily into this. Two weapons with similar throughput can feel dramatically different, since they have different movesets and weights. The player’s ability to utilize the best aspects of the weapon and mitigate its downsides becomes the core of a great game.
It doesn’t matter if you’re at Nintendo with 30+ years of experience or working on your first game. Exploring, iterating on and developing game mechanics and systems is the lifeblood of your game design project.
Understanding the difference between a meaningful mechanic and supporting fluff will help you invest your time, energy and budget effectively.
Identifying your core mechanics and building your secondary mechanics around them will help you find your fun gameplay loops.
Being familiar with your genre and competitors will help you meet and match audience expectations—and enable you to break free from outdated elements.
Finally, creating diverse challenges where players can apply mechanics creatively, consistently and effectively to solve problems on their own will ensure players love your game and want to replay it for years to come.
