Einstein Riddles (Puzzleship)

Einstein Riddles, also called Einstein Puzzles, put a row of houses side by side. Each house has a colour and a few other attributes, such as a nationality, a pet or a breakfast, and every item belongs to exactly one house. The clues mix direct placements with relations like next to or somewhere to the left of, and together they allow a single arrangement.

Puzzleship's version lets you choose each answer directly from the house it belongs to, with an emoji beside each item so clues and houses are easy to match. Sizes grow with difficulty, from four houses and four attributes up to five houses with seven, and the attributes change from puzzle to puzzle. The wording matters: next to means either side, while directly to the left pins the pair together.

Puzzleship publishes six Einstein Riddles a day, graded from very easy to ultra hard. Each day's riddles are numbered and dated, the same for every player, and go up at 13:00 UTC, although the page says midnight in your own time zone; earlier days stay playable in the archive. The site is free with ads, and a premium plan removes them.

Each clue in the list has a box you can tick once you have used it, which helps on the longer lists. On a phone the four or five houses sit side by side in narrow columns with the clues below them.
