ZeroSum: Math Tile Rush

ZeroSum is a numbers puzzle stripped down to its fastest idea: a target appears, and you tap tiles until they add up to it exactly. Land it and the tiles pop, the board falls in behind them, and the clock gains three seconds. Overshoot it and the whole combination burns off the board while the target flashes red. When the countdown reaches zero, the run is over. That is the entire rulebook. Everything after it is nerve. HOW TO PLAY • Tap tiles on the 5x5 board to build a running sum. • Match the target exactly to clear those tiles and win +3 seconds. • Go over, and the tiles you picked burn away with no time back. • Keep the clock alive for as long as you can. EVERY TARGET IS SOLVABLE Targets run from 1 to 99, and one never appears unless the board in front of you can actually reach it with two to four tiles. No dead ends, no unlucky boards. THREE WAYS TO PLAY • Classic — the sixty-second original. • Arcade — Blitz, Wipeout, Chain Rush and Zerosum, each bending one Classic rule. • Abacus — numbers flash one at a time; add them in your head before the window closes. WHEN YOU ARE STUCK • Hints highlight a winning combination. • Auto fills solve the current target outright. • Head starts put +10 seconds on the clock. • Out of time? Revive and keep the run going.

DRAWN, NOT DECORATED The chalked-maths wallpaper and the sticker tiles are painted by the game itself rather than shipped as images, so the board stays sharp on every screen and the download stays small. Sum the tiles. Beat the clock.
