v1.1.3: leaderboards + 3 game modes. Can you clear the grid before it overflows? 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

========================== THREE MODES, ONE GRID

EASY — No pressure. Practice at your own pace. CLASSIC — From turn 10, a new row pushes in. Stay ahead of it. HARDCORE — Both sides push simultaneously. Every move counts.
