Numbra

Numbra is a number puzzle game built around one idea: spotting the rule nobody told you. Each puzzle places numbers inside a geometric shape — a triangle, a hexagon, a pyramid, a grid. One cell is empty. Your job is to work out what connects the others and fill in what belongs there. Sometimes it is a sum. Sometimes a product hiding along a diagonal. Sometimes a sequence that only makes sense once you stop reading it row by row. No timers pushing you. No lives to run out of. Just you and the pattern. 150 HANDCRAFTED LEVELS Every level was designed and verified by hand, then ordered from gentle to genuinely difficult: 30 easy, 50 medium, 40 hard and 30 expert. No filler, no repeated puzzles. Solve a level without spending a hint and you earn all three stars. NEW PUZZLES EVERY DAY Ten fresh puzzles are generated daily — three easy, four medium, three hard. Everyone in the world gets exactly the same set, so you and your friends can compare notes. Finish the set to keep your streak alive. ACHIEVEMENTS WORTH CHASING Fifteen badges, from your first solved level to clearing every expert puzzle: hint-free runs, sub-30-second solves, three-day and thirty-day streaks. Your progress is stored on your device and survives restarts, updates and theme changes. HINTS WHEN YOU WANT THEM, NEVER WHEN YOU DO NOT Stuck on a puzzle? Spend a hint token for a nudge toward the rule, or reveal the full explanation. You start with three tokens and earn more as you progress. Every solved puzzle ends with a plain-language explanation of the pattern, so a hard level teaches you something instead of just blocking you. DESIGNED TO BE LOOKED AT Dark and light themes that follow your system setting, soft gradients, spring animations and typography chosen so numbers stay readable at a glance. Sound and vibration are separately switchable — play in complete silence if you prefer. PLAYS OFFLINE No account. No sign-up. No connection required. Open the app on a plane, in a tunnel or with mobile data off and every level, daily puzzle and achievement still works. FAIR BY DESIGN Ads never interrupt a puzzle in progress. Watching a rewarded ad is always your choice, never a requirement — and you get one free level skip every day whether you watch anything or not. There is no banner on the game screen. Numbra is free, made for people who like the quiet satisfaction of a pattern clicking into place. Available in English and Turkish.
