About

Ottomino

Features
Read full description

Ottomino is a block puzzle with one rule that changes everything: every day the whole world gets the same 8×8 grid and the same sequence of pieces, and everyone has a single attempt. That is why scores can actually be compared. HOW IT PLAYS • 8×8 grid, three pieces in hand at a time. • Pieces cannot be rotated: placement is the whole game. • A full row or column clears; several lines at once, or on consecutive moves, build the multiplier. • The run ends when none of the three pieces fits anywhere. • No timer: this is spatial logic, not speed. A game lasts three to five minutes. THREE WAYS TO PLAY • Daily challenge — one grid, the same for everyone, one attempt. It resets at midnight UTC. At the end you get your percentile, a rank from Wood to Grandmaster, and your position among the people who played near you. • Training — no limits, your own record is the opponent. • Groups — a private group joined by code or link: everybody plays the identical round and the app ranks the group. THE ZONE ARENA No global list of strangers: the app looks for the smallest ring around you containing at least five real people — town, 10 km, 25 km, province, region, country. It widens on its own until it finds them, so it is never empty and never anonymous. AI players are always labelled as such and are never counted as people. IN PRACTICE • Free. One full-screen ad when a run ends, never during play, and no ads at all for players under 16. • No account, no email, no login. • Every game can be replayed move by move. • Eight languages: Italian, English, French, German, Spanish, Portuguese, Dutch, Polish. • iPhone and iPad: on a tablet in landscape the board and the pieces sit side by side. The name comes from otto, Italian for eight: eight columns, eight rows.
