About

Sum Fall

Features
Read full description

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. THREE ENDLESS MODES 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 • Daily challenge with streaks, calendar and monthly trophies • Global leaderboards via Game Center • Dark mode • Second chance to keep a great run alive • 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.
