About this game

ncrement is a fast, arcade-style mental-math game that turns simple arithmetic into a reflex sport.

The rule is dead simple: you're shown a number and an instruction — "add 1 to each digit." Type the transformed number
on the keypad before the timer runs out. So 125 becomes 236. Easy? Now do it in a second and a half. Now the digits
roll over, so 9 becomes 0. Now it's +2, then +3. Now there are more digits — up to four.

THREE WAYS TO PLAY
• Classic — endless escalation. Build streaks, level up, survive three misses.
• Speed — the clock shrinks with every correct answer. How long can you keep up?
• Levels — a ladder of hand-paced challenges. Clear each level, unlock the next, and watch your map of conquered
levels grow.

Nail answers in a row to build streaks and level up — bigger numbers, bigger increments, less time on the clock. Miss
three and the run is over. Then you do the only reasonable thing: play again.

FEATURES
• Three modes: Classic, Speed, and a Levels ladder
• One-more-go arcade loop — quick runs, instant restarts
• Escalating difficulty: up to four digits, bigger increments, a tighter timer
• Digit roll-over (9 → 0) that keeps your brain honest
• Tracks your best score and best streak per mode
• Clean, high-contrast design built for one-handed play
• Optional one-time "Remove Ads" upgrade

No accounts. No fluff. Just you, the numbers, and the clock.
Fast mental-math arcade: add to each digit before the clock runs out.
