The snake moves one cell per step on an 18 by 18 board that scales to the screen, so it fits even a 320 pixel phone without scrolling. Swipe on the board or use the arrow pad below it on a phone; use the arrow keys or WASD on a computer, and Space to pause. Turns are queued, so two quick presses inside one step both take effect in order instead of folding the snake back into itself. A new game waits for your first direction before it starts moving, and switching to another tab pauses it.
With space hints on, every step counts how many free cells each possible turn leads to. Any area smaller than your body is shaded amber and the bar under the board says which way still has room, because once the head enters such a pocket it runs into the body before the tail can clear the way. The count is a warning, not a guarantee: the tail keeps moving, so a tight squeeze can still open up. When the game ends, the result card names the cause: hitting the wall, biting yourself, or trapping yourself by entering a pocket that was too small, with the time you turned into it. Scores count one point per food. The best score for each speed and wall combination is kept in this browser only; there is no online leaderboard or account.
Common questions and answers about this topic.
Swipe on the board or use the D-pad below it on a phone. On a computer, use the arrow keys or WASD. A new game waits for your first valid direction before moving, so you can get ready before you start.
Start with Relaxed to practise turning and leaving room for your body. It stays at 5 cells per second. Standard starts at about 7 cells per second and speeds up every 5 food eaten. Fast starts at 10 cells per second and also speeds up every 5 food.
With solid walls, moving outside the board ends the game. With wrap-around walls, leaving one edge brings the snake out at the opposite edge. In both modes, hitting your own body still ends the game, so watch where your body is after wrapping around.
Space hints count the connected free cells you can reach in each possible direction. The body blocks the count, except the tail segment that will move away next. An area with fewer cells than your length is shaded amber as a warning. The tail keeps moving, so tight spaces may open up. Hints do not guarantee safety or a win.
Press Pause during a game; on a computer, you can also press Space. Switching to another browser tab pauses the game automatically. When you return, press Resume to keep playing.
Each food is worth 1 point. When a game ends, the best score for each speed and wall combination is saved in this browser only. There is no online leaderboard or account sync across devices. Leaving an unfinished game does not save that round or its score as a record.
