Increment is a fast, arcade-style mental math game that turns simple arithmetic into a test of speed and reflexes. The rule is simple: you're shown a number and an instruction, such as "Add 1 to each digit." Type the transformed number before the timer runs out. 125 → 236 Easy? Now do it in a second and a half. Then the digits roll over, so 9 becomes 0. The increment grows to +2, then +3. The numbers get longer and the clock gets shorter. VS: RACE A FRIEND Play 10 numbers and send the link. Your friend gets the same 10 numbers with your time on the clock for each one, so every number is a race. The faster answer takes the point. Pick an avatar and your country flag; they appear on every challenge you send. Works between iPhone and Android, no account needed. DAILY One puzzle a day, the same 20 numbers for everyone. Keep your day streak going and share your result grid. MODES • VS: race a friend's time on the same 10 numbers • Classic: build streaks, level up, three misses and you're out • Daily: one shared puzzle a day FEATURES • Player profile with your avatar, flag and stats • Quick runs and instant restarts • Game Center leaderboards for Classic and your Daily streak • Digit roll-over (9 → 0) that keeps every answer honest • Clean, high-contrast design built for one-handed play • Optional one-time Remove Ads upgrade No accounts.
