ZEBRA

Read full description

Five houses in a row. Who keeps the zebra? ZEBRA takes Einstein's famous riddle and generates a fresh one every time โ€” always exactly one answer, always reachable by logic alone. Read a clue, rule something out, and watch the last house fall into place. Also known as the Zebra Puzzle or Einstein's Riddle, this is the logic grid puzzle with a twist: you're not just matching pairs, you're working out the order. Left, right, next to, at the end. โ—† Exactly one answer, never a guess Every puzzle is checked by the built-in logic engine before you see it: one unique solution, reachable by deduction alone. Puzzles that fail either test are never shown. โ—† Deduce the order, not just the pairs - The ivory house is immediately to the left of the green house - Milk is drunk in the middle house - The Norwegian lives next to the blue house Combine clues like these to pin down the row, one house at a time. โ—† Features - Four sizes: 3, 4, 5 and 6 houses.
