Five houses in a row. Who keeps the zebra? ZEBRA takes Einstein's famous riddle and generates a fresh one every time — 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. ◆ 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. ◆ 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. ◆ Features - Four sizes: 3, 4, 5 and 6 houses. Five is the size of the original riddle - The original Einstein zebra puzzle, included - A visual row of houses that fills in as you solve — roofs take their colour once you know it - A question for every puzzle, and houses that light up when you finish - Tap a clue to highlight the houses and cells it refers to; fully used clues dim automatically - Logic hints: the next square you can deduce, and the clue numbers that prove it - Daily Challenge: one shared puzzle for everyone, every day - Weekly Challenge: a new six-house puzzle every Monday - Past dailies: play any day you missed from the calendar - Ranks from Novice to Master Detective, plus nine badges - Auto-X, notes, undo, and continue where you left off - Themes: Classic, Forest, Street, Station, Harbor - Adjustable clue text size and dark mode - English and Japanese ◆ Perfect for - Anyone who has solved Einstein's riddle on paper and wants more - Players who want a different puzzle every time, not one classic recycled - Fans of logic grid puzzles, sudoku and brain teasers looking for something deeper - Players who'd rather learn how to think through a puzzle than be told the answer - A quiet, offline brain game for commutes and flights ◆ Peace of mind - Free to start.
