Sum Fall: Number Puzzle

Sum Fall is the arithmetic puzzle game that plays by its own rules. Place numbered pieces on the grid. Watch them fall — up or down, you never know which way. When two pieces meet and their values add up to 0 or 10, they vanish. Clear them all before the grid overflows. Simple to learn. Fiendishly hard to master. HOW IT WORKS → Each turn, choose where to place a piece in the center row → Pieces fall toward the ceiling or floor — direction is a mystery → Adjacent pieces fuse: green (+) adds, red (−) subtracts → Result is 0 or 10? Both pieces vanish and you score → Chain vanishes for multiplier bonuses: ×1.5 → ×2 → ×3 → ×5 NEW — DAILY CHALLENGE One handcrafted puzzle a day — the same for every player.
