iPhone
What's your real math IQ? Tap to collapse equations until they equal the target. Now with Marathon — endurance puzzles, one slip ends it.
Real math IQ in 60 seconds. Compete. Train. Or run Marathon until you slip. Daily challenge, same for everyone.
The rules are simple. You're given an equation built from numbers and operators. Tap a number to remove it — along with the operator beside it — and the expression collapses around your choice. Your goal: leave behind an expression that evaluates to today's target.
That's it. One move at a time. No hints, no clutter, no chaos.
— FIVE WAYS TO PLAY —
DAILY CHALLENGE
A new puzzle every day at midnight. Everyone in the world gets the same one. See where your time ranks against the global field, and keep your streak alive.
COMPETE
Five puzzles, against the clock. Each solve earns time bonuses; each mistake costs you points. The cleaner you play, the higher you climb on the leaderboard.
TRAINING
Same gameplay, no timer, infinite plays. Practice the patterns, learn the shortcuts, get faster without pressure.
FRIEND CHALLENGES
Send any puzzle to a friend with your solve time attached. They play the same board, and it pings back to you with their time.
QUICK SOLVE
Drop in for 60 seconds. Drop out without losing progress. Designed for elevators, coffee lines, and the bathroom.
— DESIGNED LIKE A GAME, NOT AN AD —
Calm gold-on-black aesthetic, serif numerals, tactile haptics, percussive sounds. No popups. No fake urgency. No "spin the wheel for coins."
