About the Game
This Tetris-like block puzzle game is the only one that adds up. Adds up to zero.
Numbered pieces ranging from negative to positive values that widen the further you get drop onto the grid like a classic block-stacker. But a line or square doesn't clear just because it's full: it only clears once the sum of its values equals zero. Full horizontal rows clear as lines, while 2×2 up to 4×4 regions clear as squares (bigger squares score more). Drag corner-to-corner on the board to preview a square's running sum before you commit. Every 10 clears bumps the level, widening the range of numbers in play and making zero-sums harder to build.
Two ways to play
- Daily Challenge: Easy, Medium, Hard, Insane...each starting from a different pre-filled board and level. Clear the bottom row once per difficulty per day for a credits reward.
- Arcade: Start from an empty board at level 1 with no time or clear limit! A pure high-score chase, with every power-up (including permanent ones) available and your run auto-saved.
Features
- Zero-sum clear condition for both full lines and squares up to 4×4, with a corner-to-corner sum preview
- Three power-ups: Make It Rain, Close Enough, and Zero It Out...buy with earned credits, or earn free by watching a rewarded ad
- Unlockable Stored Piece (hold) mechanic, plus a second hold slot for deeper strategy
- Local high scores per mode and difficulty, plus an optional global leaderboard on mobile
What Makes It Different
Clearing means summing.
Lines and squares don't clear just because they're full: the numbers on the pieces have to add up to zero first. It's the one mechanic no other block-stacker has.
Two ways to play.
Daily Challenge brings a structured, once-a-day puzzle across four difficulties; Arcade is an open-ended, no-limit high-score chase. Same core mechanic, two very different challenges.
Fair, not pay-to-win.
Power-ups and the hold mechanic add a light strategic layer. Everything is available after earning enough credits, or pay only unlock them earlier.

Short
Zerosion is a falling-block puzzle game where clearing isn't about filling space: lines and squares only clear when their numbers add up to zero.
Long
Zerosion is a falling-block puzzle game where clearing isn't about filling space: it's about making the numbers add up to zero.
Numbered pieces drop onto the grid Tetris-style, but a line or square only clears once the sum of its values equals zero: full rows clear as lines, and 2×2 up to 4×4 regions clear as squares, with bigger squares scoring more. Difficulty escalates as you clear, widening the range of numbers in play.
Two ways to play: Daily Challenge (four difficulty tiers, one clear per day, Credits rewards) and Arcade (an open-ended, empty-board high-score chase). Power-ups, an unlockable hold mechanic, and local plus optional global leaderboards round out the experience. Monetization is ad-supported and convenience only. No interstitials, no pay-to-win.
