Jump, match, build, or explore? How to find your core game loop

Think about the last game you couldn’t put down. Strip away the story, the art, and the music, and you’ll find one small action you did hundreds of times – a jump, a swap, a tap on a crop that’s ready to harvest. That action, and the short cycle around it, is your game’s core game loop.

It’s also one of the first big decisions you’ll make when building your first video game. You don’t need to write code or learn a game engine to build your game, but you do need to know what your player will spend their time doing. By the end of this post, you’ll have yours written down in a single sentence.

What is a core game loop?

A core game loop is the short, repeatable cycle of actions a player performs most often in a game. Game designer Alexander Brazie describes a gameplay loop as a repeatable sequence of actions that makes up the primary flow of play, and the core loop as the one upon which all other loops are built.

Most core loops share the same three-beat shape: a challenge, an action, and a reward. For example, in a classic platformer, it’s spot a gap, leap, survive – and repeat. The reward (landing safely) sets up the next challenge (the next gap), which is what makes it a loop rather than a list.

Bigger games stack loops on top of each other. Brazie suggests thinking in four timescales: moment to moment, minute to minute, hour to hour, and day to day. Clearing a level, unlocking a new area, and coming back tomorrow are all loops too. But they all sit on the innermost one, so that’s where you start.

Start with a verb: jump, match, build, or explore

The fastest way to find your video game’s core loop is to pick a verb. Not a theme, not a story – a verb. Here are four common core game loops, and the decisions each one hands you.

Jump

Jump games test timing and movement. The jump game loop is to spot an obstacle, jump, land, repeat. If you pick jump, you’ll need to decide how high and how far your character goes, how forgiving the landings are, and what gets in the way.

Match

Match games test pattern-spotting and planning. In a match-3 game loop, for example, you must swap pieces, plan your next move, and watch the board refill; combos and chain reactions are where the surprise comes in. Your decisions: board size, what counts as a match, and how a level ends – a move limit, a score target, or a cleared board.

Building/crafting

Building and crafting games reward patience and creativity. Examples include the explore, harvest, and craft loop, and the plant, harvest, and sell loop. If you pick the build loop, decide what players gather, what they can make with it, and what they’re building toward.

Exploration

Exploration games run on curiosity. Unity Learn breaks the adventure loop into three steps: explore the world, complete tasks or challenges, and earn rewards or unlock progress. Exploration-focused games lean on detailed environments and hidden rewards, so your big decisions are what’s worth finding and how you’ll hint at where it is.

Lean into genre

Once you’ve got a verb, you’ve probably got a genre, too – and that’s a good thing. A genre is a loop players already know. They walk in understanding the controls, the goal, and what a reward looks like, so you spend less time teaching and more time making the loop feel great.

Familiar doesn’t mean crowded out, either. Puzzle was the only top casual mobile genre to grow in 2025, passing $8.2 billion in revenue, and newer puzzle styles like sort, screw, and block puzzles are among the fastest-growing segments. Players keep coming back to loops they love, which leaves room for your fresh take on one.

Test your core game loop in 30 seconds

Before you build anything else, run your core game loop through these four questions:

• Can you say it in one sentence? If it takes a paragraph, it’s probably several loops tangled together.
• Is the goal clear without instructions? GameAnalytics recommends one main objective that players can understand from the mechanics and the game world alone.
• Is the action satisfying by itself? Aim for a loop that’s easy to grasp and hard to master. The jump, the swap, or the harvest should feel good even with nothing else around it.
• Does the reward lead back to the challenge? If the reward doesn’t set up the next round, you’ve got a sequence, not a loop.

Then play it as soon as you can. There’s always a gap between how you imagine a game will feel and how it plays in practice. And as your game grows, keep using the loop as a filter: if a feature doesn’t strengthen it, cut or rethink that feature.

Closing the loop: wins, losses, and “again?”

Every loop needs an exit. Win and lose conditions define when the loop ends, while smaller loops live inside it. You don’t need to code those rules, but you do need to decide them. Before you start building, answer three questions:

1. How does a player win a round?
2. How does a player lose one?
3. What makes them want to press “play again”?

That third question is where your loop becomes a game people return to.

Your turn

Grab a notebook and fill in this sentence:

In my game, you ___, then ___, so you can ___.

If your sentence starts with jump, match, build, or explore, you already know your genre, your controls, and what your player will do a 1,000 times.
