CalcFor.Fun

Math meets arena combat in CalcFor.Fun, a multiplayer twist on the cell-growth formula. Every player carries a hidden math problem on their cell. Tap an opponent to reveal their equation while exposing your own to them.

Race to solve the enemy's problem before they crack yours. A correct answer eliminates them; a wrong one ends your run. Your equation refreshes after each attempt, and problems grow harder as your cell expands. Earn hearts by defeating rivals—each heart forgives one mistake, and taking down hearted opponents can grant more.

Global rankings track your best ten scores from recent matches. Outthink the field and climb the leaderboard.
