Snake Game

Steer the snake to eat food and grow longer without hitting the walls or yourself. In math mode, several numbers appear and you must eat only the multiple of the target, such as a multiple of 7. Eat a wrong number and the game ends.

How to play

1. Press Start. Use the arrow keys (or W A S D), swipe on the board, or tap the buttons.
2. Eat food to grow. Hitting a wall or your own tail ends the game.
3. In math mode, read the target (“Eat a multiple of 6!”) and eat only the number that is a multiple.

Divisibility shortcuts for math mode

• 2: the last digit is even.
• 3: the digits add to a multiple of 3 (57: 5 + 7 = 12, so yes).
• 4: the last two digits form a multiple of 4.
• 5: ends in 0 or 5.
• 6: passes the tests for 2 and 3.
• 9: the digits add to a multiple of 9.

Strategy

Move in wide loops and keep open space near your head. As the snake grows, follow the walls in a zigzag so you never trap yourself.
