About this game

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.
