👑 How to Play
Fill an 8×8 board by placing 8 Queens and 2 Kings. Each puzzle has exactly one solution.
♛ Queens
- Place one queen in each colored region (estate).
- No two queens may share the same row or column.
- Queens cannot be adjacent to each other (including diagonals) — but they can share a long diagonal.
♚ Kings
- Both kings go on gray cells only.
- Kings cannot be adjacent to or on the same diagonal as any queen (at any distance).
- Kings cannot share a row, column, or diagonal with each other.

💡 Hints
Stuck? Tap the Hint button — it won't just tell you the answer, it'll explain why.
- Each tap reveals a little more: first a nudge, then the reasoning, then the answer.
- Hints walk you through the exact logic — which cells conflict, which estates are confined, what chain of deductions leads to the elimination.
- For longer chains, steps are revealed one at a time so you can follow along.
💡 Don't be afraid to use hints! They act as an in-game tutorial — each one teaches you a solving technique you can apply on your own next time.
📊 Difficulty
25 handcrafted puzzles across five tiers — from gentle introductions to fiendish chain-reasoning challenges.
- Beginner — queens can be placed without using king logic
- Easy — kings are necessary to solve the full puzzle but are still fairly trivial
- Medium — more complex interaction between kings and queens
- Hard — long deduction chains, set logic
- Expert — deep chains, king pairing traps, cascade reasoning
