Zebra
Read a clue. Cross off what it rules out. One arrangement survives.
A daily logic-grid game — the classic "the doctor lives in the red house" puzzle. Every case is proved before it reaches you: exactly one solution, always reachable by reasoning, never a guess. Four tiers named after the technique each one asks for. Offline, five languages including Kurdish Sorani.
Key Features
What makes Zebra great
Proved before it reaches you
The generator computes the exact deduction depth each case requires and confirms a single solution. Boards that would force a guess never ship.
Tiers that name the technique
Cross off, chain, work out before-and-after, test a possibility — four tiers named for what they ask of you, not a star count.
Clues in five languages
The clues are the puzzle, so they are written natively in English, German, Arabic, Persian and Kurdish Sorani, with real RTL layout.
