Sum Fall: Number Puzzle

v2.0: DAILY CHALLENGE & DEMOLITION! A new puzzle every day — same for everyone — plus endless demolition levels full of golden cells. Place. Fall. Fuse.

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. Clear the board, race the clock, earn up to 3 stars. Keep your streak alive, replay past days from the calendar, and complete a full month to earn a trophy.

NEW — DEMOLITION An endless series of solvable puzzle levels. Destroy every golden cell with a limited piece budget. Bombs, armored cells, mystery values, cyclic counters… plan your chains, finish under par, claim all 3 stars.
