Kairu's Number Snake
The rule changes every five seconds — eat only the numbers that fit it. Multiples, factors, primes, squares… one wrong bite and it's over.

How to play — a rule like “Eat: Multiples of 3” sits up top and changes every 5 seconds. Steer with ↑ ↓ ← → (or W A S D, swipe, or the buttons) and swallow only the numbers that fit the rule. Grab a 🍱 box lunch any time for free points. Bite a number that doesn't fit and it's game over. Clear a full lap of all the rules and the snake speeds up. How long can you survive?
Practice Run
Pick one grouping to drill. The rule won't rotate — just steer and sort. Practice never touches your best or the leaderboard.
