digito. is a calm, minimalist math puzzle. One target number. One digit. Endless ways to get there.
Reach the target using only a single repeated digit and a handful of operators — add, subtract, multiply, divide, roots, and concatenation. The trick? The fewer digits you use, the better you score. There's always a sharper, more elegant answer to chase.
No timers shouting at you. No clutter. No account needed to play. Just you and the numbers, for thirty seconds or thirty minutes.
— HOW IT PLAYS —
• The expression evaluates as you type — hit the target and the level just opens.
• Score on elegance. Every solution counts, but fewer digits ranks higher.
• Hints when stuck. Optional nudges point you toward a path without spoiling the solve, so you never hit a dead end.
— WAYS TO PLAY —
• Daily challenge — a fresh target every day, ranked by fewest digits then speed. Resets at midnight.
• Weekly flagship — build the week's target with each digit 1 to 9. Nine worlds, one shared goal, a global leaderboard.
• Number worlds — pick a digit and climb its puzzles at your own pace. Your progress, your best solutions.
— DETAILS —
• Light "Notebook" and dark "Ink" themes, both on a signature graph-paper grid.
• Speaks twenty languages out of the box.
• Free to play.
Simple to learn. Hard to perfect. Reach the number your way.
