RiddleHouses is the classic "Einstein's Riddle" logic puzzle, brought to life as a clean, modern drag-and-drop game — now with three difficulty levels, so you can warm up before taking on the original.

THREE LEVELS, THREE PUZZLES
• Easy — 3 launch pads, 6 clues. Work out who flies which ship, and to which planet.
• Medium — 4 islands, 11 clues. Match each pirate with their gear, treasure, and animal.
• Hard — the original: 5 houses, 5 categories, 15 clues. Exactly one answer: who owns the fish?

HOW IT WORKS
Drag cards from the Cards panel onto the board. Every placement is checked against the clues in real time — if two cards conflict, you'll see it immediately, so you're always reasoning forward instead of hunting for a mistake three moves back. Tick off clues as you use them to keep track of your progress.

FEATURES
• Real-time conflict checking as you place each card
• Clue checklist with a progress bar
• Undo your last move or reset the board at any time
• Built-in timer to track your solving time
• Stuck on Hard? Ask for an AI-generated hint (up to 3 per game) that nudges you toward the next deduction
• Light and dark themes
• "How to Solve" and "Rules" guides for newcomers
• A jigsaw-puzzle intro with three levels to warm up — replay it anytime from the menu
• Play in English, Ukrainian, Norwegian, German, French, or Spanish
• Your progress is saved automatically on each level
• No ads, no account required — just the puzzle

WHO IT'S FOR
If you like Sudoku, logic grids, or a slow, satisfying "aha" moment, this is your kind of puzzle. Start on Easy to learn the method, then see if you can crack the original. It rewards careful reading and clean deduction, not speed.

Install RiddleHouses and see if you can work out who owns the fish.
