Sum Fall: Number Puzzle

Math Grid Strategy Game

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

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. ========================== POWER-UPS ========================== • Reveal Directions — see where all pieces will fall before committing • Change Direction — flip a piece's trajectory • Change Value — set any piece to the number you need (1–9) • Change Operation — switch + and − to make the math work for you • Storage — hold a piece aside and use it later ========================== FEATURES ========================== • Global leaderboards via Game Center • Offline play — no Wi-Fi needed • Auto-save — resume any game where you left off • Lives system — regenerate over time (infinite in Premium) • No account required • English, French, Spanish, German, Portuguese ========================== PREMIUM (OPTIONAL) ========================== Remove ads, unlock infinite lives, and get an extra charge for every power-up. One purchase. No subscription. No tricks. Think you can top the leaderboard? Prove it.
