Divide the falling numbers by primes until they disappear. An 84 lands. Tap 2 → 2 → 3 → 7. The instant it reaches 1, the tile shatters. ■ Three ways to play - Endless: survive the rising board and chase your high score - Stages: 100 stages, each with its own goal, from "clear every star tile" to "reach a 22 combo". Every chapter twists the rules: only 2s and 3s, no 2s at all, items everywhere - Items: Bomb, Cross, ÷ Storm and Fever. Clear a tile that carries an item to trigger it, and anything it catches can set off the next one ■ This is not a math drill It is a board management puzzle. Which number do you attack first? Which tiles do you clear together? When do you deal with the expensive large primes? Guess wrong and the board chokes. ■ Divide them together Tiles that share a prime factor can be selected and divided in one move. Three at once scores nine times as much. They burst one after another, and you feel every one of them in your hand. ■ A miss will not kill you outright Press a prime that does not divide and the board rises. One mistake is not the end. The pressure builds, and pulling a collapsing board back from the edge is the best feeling in the game. ■ You can feel yourself improving At first, 84 stops you cold. After a while, 2² × 3 × 7 appears instantly. That difference becomes your score. - A few minutes per run, one-handed - Crafted haptics and effects on every clear (haptics can be turned off) - Ads are kept light, and a one-time purchase removes them for good - Game Center leaderboard supported
