How to Play
- Start a run. Press any arrow key, tap the start button, or hit Space. On a phone the start button covers the whole board, so a single tap is enough.
- Steer the snake. Use the arrow keys or
W/A/S/Don a keyboard, or swipe in any direction on a touchscreen. The snake can never turn back into its own neck, so a fast double input is safe. - Eat the pickup. Every pickup adds the current multiplier to your score and makes the snake one segment longer.
- Chain your combos. Grab the next pickup within 2 seconds and the multiplier steps up, to a ceiling of x8. The bar under the score shows how much of the window is left.
- Grab the phase ring when it shows up. The rare violet ring banks one pass through your own trail. It lasts 11 seconds on the board.
- Pause any time. Space or the Pause button freezes the run; switching browser tabs pauses it for you.
- Beat your best. Each mode tracks its own best score, and your last five runs are listed beside the board.
Features
- Combo multiplier up to x8 on a 2-second window, with a live countdown bar and a trail that brightens as the chain grows.
- Three modes — Classic, No Walls, and Speed Rush — each with its own saved best score.
- Rare phase pickup that lets the snake pass through its own trail one time.
- Interpolated 60fps movement, so the snake glides between grid cells instead of stepping from square to square.
- Particle bursts, a short screen shake on death, and a CRT scanline overlay for the arcade feel.
- Three synthesized sound effects built with the Web Audio API — no audio files are downloaded. Sound is muted by default and there is a speaker toggle.
- Keyboard, WASD, and swipe controls, plus a large tap-to-start target on mobile.
- Runs offline after the first load and stores your best score and last five runs in your own browser only.
- Accessible by design: full keyboard operation, visible focus rings, text contrast above the WCAG 2.1 AA 4.5:1 threshold, no flashing above 3 Hz, and honors your reduce-motion setting.
Frequently Asked Questions
Is Neon Snake Arena free to play?
Yes. Neon Snake Arena is completely free and there is nothing to buy. No account is required, there is no sign-up form, and no email address is ever requested. Open the page and press an arrow key to start.
How does the combo multiplier work?
Every pickup starts a 2-second timer. Eat the next pickup before that timer expires and the multiplier goes up by one step, to a maximum of x8. Each pickup adds the current multiplier to your score, so an x8 pickup is worth 8 points instead of 1. Let the 2 seconds lapse and the multiplier drops back to x1. The bar under the score shows exactly how much of the combo window is left, and the snake's trail glows brighter as the multiplier climbs.
What is the phase pickup?
The phase pickup is a rare violet ring that appears occasionally alongside the normal pickup and disappears after 11 seconds if you ignore it. Collect it and you bank a single pass through your own trail: the next time you would hit your own body, the snake slides through it instead of dying. The charge is spent on that one pass and you have to find another ring to get it back. It does not protect you from walls in Classic or Speed Rush.
What is the difference between the three modes?
Classic is the standard game: hitting a wall or your own trail ends the run. No Walls removes the edges — leave one side of the grid and you reappear on the opposite side, so only your own trail can kill you. Speed Rush keeps the walls and speeds the snake up every 10 points; it never slows back down, so the combo window gets harder to hit as the run goes on. Each mode keeps its own best score.
Does Neon Snake Arena work offline?
Yes. The page registers a service worker that caches the HTML, stylesheet, and game script on your first visit, so it runs offline afterward. Your best score per mode and your last five runs are saved in your browser's localStorage, which means they survive a reload but never leave your device. Nothing is uploaded and there is no server-side save.
