How to play Zebra Puzzle
- The zebra puzzle — often called Einstein's riddle — asks you to match five houses with their owner, colour, drink, pet, and hobby using only a list of clues.
- Each attribute value belongs to exactly one house, so a logic grid of Xs and ticks lets you eliminate possibilities until only one arrangement remains.
- Cross-reference clues like "the person who drinks coffee lives next to the green house" until the full solution — including who owns the zebra — is forced.
- Every puzzle is generated from a seed with a guaranteed unique solution, and a New puzzle button deals a fresh set of clues.
