How to make a snake game
In a snake game, the player steers a head that never stops moving, and the body follows the exact path the head took. Eating makes the snake longer; hitting a wall or a body ends the run. The classic version moves cell by cell on a grid; the .io version glides freely in an arena full of rival snakes, where cutting another snake off with your body is how you win.

A prompt to build your first version
Copy it into EvonX, or send it from the box at the end of this page. Change the theme, the numbers and the twist to make it yours.
Create a snake arena game where I steer with a joystick, eat glowing pellets to grow, rival snakes die when their head hits my body and turn into pellets, I can hold a button to boost at the cost of length, a leaderboard ranks everyone by length, and each level asks me to reach a length before the clock runs out.
Other directions to try:
- A classic grid snake with swipe controls, wrap-around walls and a speed-up every five apples
- A neon space snake arena where rivals are robot worms and power-ups give a short magnet
How snake games work
Both kinds of snake game share the same core idea: the body is a record of where the head has been. What changes is how movement and collisions are measured.
Classic snake moves on a grid
The snake is a list of cells. Each tick, add a new cell in the current direction at the front and remove one from the back. When it eats, skip the removal once, which grows it by one cell.
.io snake glides along a path
The head moves continuously and turns at a limited rate. The body is drawn as segments spaced along the head's recent path, so the snake curves smoothly instead of turning in right angles.
Collisions end the run
In the classic game, hitting a wall or your own body ends it. In arena games, your own body is usually safe, but touching another snake's body with your head kills you.
Death feeds the arena
In .io games, a dead snake turns into a trail of pellets. Cutting off a large rival is the fastest way to grow, which is what creates the risk-and-reward of the genre.
Boost trades length for speed
Holding boost makes the snake faster but sheds length as pellets. It is the main tool for cutting rivals off and escaping traps.
Step by step: building a snake game
These steps cover the arena version, which is what most players mean by a modern snake game. The classic grid version stops after step three.
1. Steering and movement
Move the head at a constant speed. Turn it toward the joystick direction at a maximum number of degrees per second so it cannot reverse instantly.
2. A body that follows the path
Record the head's positions. Place each body segment at a fixed distance back along that recorded path. Store positions in a ring buffer so long snakes stay cheap.
3. Pellets and growth
Scatter pellets across the arena and respawn them over time. When the head passes over one, increase the length by a set amount.
4. Fast collision checks
With many snakes and hundreds of segments, check head-to-body contact through a spatial hash so each head only tests nearby segments.
5. Rival snakes
Start with simple bots that wander toward food and avoid bodies ahead of them. Add bolder ones that try to circle or cut off smaller snakes.
6. Death, pellets and boost
On death, convert the body into larger pellets along its path. Add a boost that raises speed and drops pellets from the tail while held.
7. Leaderboard and goals
Rank every snake by length in a small on-screen table. For a level mode, set goals such as reaching a length, getting a number of kills, or finishing in the top three when time runs out.
8. Camera and performance
Keep the camera on the player, zoom out slightly as the snake grows, and only draw what is on screen.
Arena and level difficulty
In arena snake games, difficulty comes almost entirely from the rivals.
| Stage | What changes |
|---|---|
| Early arenas | Few rivals, all timid; plenty of food. The player learns steering and boost. |
| Middle arenas | Hunters that try to cut the player off; goals based on kills instead of length. |
| Late arenas | Fast, long rivals that boost across the player's path; rank goals with a short clock. |
| Classic mode | Raise the speed every few pellets eaten; that alone carries the difficulty. |
Build it with EvonX
1. Describe the game
Paste the prompt above or write your own. Naming the genre is enough for EvonX to start from its snake arena template.
2. Play the first version
The game runs in a phone preview next to the chat, so you can play it as soon as it is built.
3. Change it in chat
Ask for different levels, rules, art or difficulty and test each change straight away.
4. Publish a link
Published games open in mobile and desktop browsers, on the free Starter plan too (with the EvonX badge). EvonX does not package games for the App Store or Google Play.
What the snake arena template already includes
- A walled arena with pellets everywhere and rival snakes already moving
- Joystick (or WASD) steering; the snake glides and never stops
- Pellets that grow the body, and snakes that burst into pellets when their head hits another body
- A boost that sprints at the cost of length, dropping pellets behind
- A live leaderboard ranked by length
- Bot rivals that get sharper: timid grazers, hunters that cut you off, fast vipers
- 12 starter arenas with length, kill or rank goals before the clock runs out
Ways to make it your own
- Classic grid snake or free-moving arena
- Arena size, walls and obstacles
- Snake speed, turn rate and growth per pellet
- Rival behavior and how many there are
- Skins and themes: garden, neon, space
- Goals: length, kills, rank or survival time
Common problems and how to fix them
The body cuts corners or stretches
Space segments by distance along the recorded path, not by time. Time-based spacing breaks when speed changes during boost.
Long snakes make the game slow
Keep positions in a ring buffer, use a spatial hash for collisions, and draw only segments the camera can see.
The snake can turn back into itself instantly
In classic snake, ignore input that reverses the current direction. In arena snake, limit the turn rate.
Bots feel either brainless or unfair
Mix bot types: most should be cautious grazers, with a few hunters. Let hunters only chase snakes their own size or smaller.
FAQ
What is the easiest way to make a snake game?
If you want to code, the classic grid version is a common first project in any language. If you do not want to code, describe the game to EvonX and it builds an arena snake game you can play straight away.
Can I make a game like slither.io?
You can make an arena snake game with rivals, boosts and a leaderboard; these are genre mechanics. Use your own name, skins and art rather than another game's assets.
Is the EvonX snake game multiplayer?
No. The template's rivals are bots, which makes the arena feel busy without servers or matchmaking. The leaderboard ranks the snakes in your arena.
Does it work with touch controls?
Yes. The template uses an on-screen joystick on phones and the keyboard on desktop.
