ZEBRA vs Anomaly

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. No subscription — the only purchase is a single one-time unlock - No third-party ads - Your records stay on your device. No account, no sign-in - Puzzles are generated on your device, so you can play offline.

Something aboard is off. Anomaly is a deduction puzzle in the tradition of Einstein's riddle, dressed as a mystery on a research station in orbit. One grid, a log full of gaps, exactly one solution — and no luck involved. NEVER A GUESS Every case is built so that each step can be forced. There is exactly one solution, and a path to it that needs no trial and error. If you are stuck, you have missed something — you have not been unlucky. SIX DIFFICULTIES From introductory to extreme. The next one opens once you have solved three cases of the current level, at least one of them without a hint. Grids grow from 3×3 to 6×5. DAILY PUZZLE One case a day for everyone, with its own streak. The week is a ramp: easy on Monday, extreme on Sunday. It is never locked — full version or not. Days you missed can be caught up on in the archive; the archive is part of the full version. The streak does not count days you caught up on — it says which days you showed up. So without the archive no streak is lost, only days that are already over. HINTS THAT EXPLAIN Three stages: which log entry carries now, which cell follows from it, and finally filling it in. You pay for the look, not for the depth. Hints come from three pools — a daily allowance, the credit that solved cases earn, and purchased packs. They are spent top down: first what expires anyway, last what cost money. CONSISTENCY CHECK Is there a contradiction anywhere? The answer is exact — and limited for exactly that reason, with a cooldown instead of endless asking. BILINGUAL AND ACCESSIBLE German and English. Dynamic Type up to the accessibility sizes, VoiceOver with spoken forms of every condensed value. WHAT THE GAME IS NOT • No advertising, no tracking, no analytics, no advertising identifier • No accounts, no registration, no server — the game runs entirely offline • No subscription • No energy meter that refills, and no waiting time you can buy away PURCHASES The full version is a one-time purchase. It unlocks "Hard", "Very hard" and "Extreme" in free play, plus the note sheet, your own crew names and the archive of daily puzzles. Hints are not included — they cost the same with the full version as without, and are sold separately. Every case remains fully solvable without the full version. Emergency Lighting is a separate purchase and likewise not part of the full version: a second lighting that bathes the station in red. It changes nothing about the game. The classic one stays available to everyone, and you can switch as often as you like. Purchased hint packs are consumables and stay on the device where they were bought; the game keeps no account. The full version, by contrast, belongs to your Apple ID and can be restored.
