Sum Fall: Number Puzzle

Sum Fall is a unique math puzzle game that combines arithmetic strategy with satisfying cascade mechanics. Now with a daily puzzle challenge and an endless demolition mode packed with golden cells. WHAT IS SUM FALL? Place numbered tiles (1–9) on a 6×7 grid. Each turn, pieces fall up or down — you don't know which way until they move. When two adjacent pieces fuse and their values sum to 0 or 10, both tiles vanish and you score. Chain multiple vanishes in one turn to trigger score multipliers up to ×5. It's the number puzzle game where every placement is a calculated risk. HOW TO PLAY Place a piece in the center row each turn. The piece falls — ceiling or floor — and lands next to others. Green pieces add (+), red pieces subtract (−). If the arithmetic result is 0 or 10, the tiles disappear. Keep the grid clear before it overflows. This number game rewards pattern recognition, mental arithmetic, and strategic thinking. No timers. No tapping frenzy. Pure puzzle logic.
