Trace a path. Hit the target. CalcWheel is a new kind of math puzzle. Each level is a different wheel of numbers and operators, and you calculate by drawing: drag a path through them and the total updates live under your finger. Let go when it lands on a target — easy to pick up, and surprisingly hard to put down. One rule to know: your path counts left to right, like a pocket calculator — so if you drag 2, +, 3, ×, 4 it evaluates as (2 + 3) × 4 = 20. WHAT YOU GET • 300 levels across six packs, from Starter to Impossible • A new daily puzzle every day — gentle on Monday, powers by Sunday • Five targets on every wheel — three to pass, all five for a star • Hints that reveal a solution one step at a time • Streaks, and a calendar of everything you have solved PLAIN AND SIMPLE • Plays fully offline. No account, no ads, no timers, no lives to wait for. • Dark by default, with a light theme if you prefer one • Seven languages • No tracking and no data collection of any kind CalcWheel is free to play. CalcWheel Pro is a one-time purchase — no subscription — that unlocks all 300 levels, the full archive of past dailies, the two bonus targets on every puzzle, and 20 hints.
