MathyCrush is a casual math puzzle with a single, beautiful rule: every level hands you a target number, and you build a live equation that matches it. Tap a number tile. Tap an operator. Tap another tile. Your expression runs across the top of the screen in real time - "2 + 6 × 9 = ?" - and the moment it equals the target, the tiles crush, the board refills, your combo stacks, and a fresh target drops in. Simple rules. Endless possibilities. No typing, no menus, no dice. - HOW IT WORKS - - Every level shows a target at the top, like "= 56" - A row of operator buttons sits at the bottom: + − × ÷ % - Tap a tile → it joins your expression - Tap an operator → it becomes the active operator for the next tile - The math runs LEFT-TO-RIGHT. No PEMDAS — just the order you tap. - Made a typo? Backspace undoes the last tile. Clear (X) resets. - Wrong answer? No penalty. The board shakes, nothing is lost. Keep building. - FREE. NO ADS. NO CATCH. - MathyCrush is 100% free. Every level, every feature — yours. - No banners. No interstitials. No rewarded video. - No subscriptions. No paywalls. No locked levels. - No trackers, no ad SDKs, no third-party analytics. Happy MathCrushing
