Amaze Kings is a Queens-style logic puzzle: the same crown-placement rules as Queens, Star Battle and Crowns, with 3,900 handcrafted levels instead of one a day. One king per row. One king per column. One king per colour. And no two kings may ever touch, not even diagonally. Simple rules, deep logic. Every one of the 3,900 handcrafted puzzles has exactly one solution, and every single one is made to be solved with pure deduction. ROYAL CAMPAIGN Climb 16 kingdom packs from a cosy 5×5 Meadow to the legendary 20×20 Crown. Levels unlock one by one, each rated 1–3 stars for difficulty. PREMIUM One purchase, no subscription: no ad breaks, unlimited Zen and 1,000 levels, every kingdom pack plus 28 Premium packs. THE CROWN ROAD Solve fast to earn crowns: beat a level's crown times for 1, 2 or 3. Crowns unlock 20 special event packs, from Comet Run to the Eternal Throne. In a hurry? Watch two short ads to open the next pack early. THE ROYAL VAULT A one-time treasure for true puzzle royalty: 86 vault packs with 2,150 extra levels, yours forever. ZEN MODE No clock, no score, no pressure. Endless boards for a quiet mind. MADE TO FEEL GOOD • Buttery drag-to-mark controls with smart auto-crosses • Hints when you're stuck • Dark & light themes, subtle sound and haptics • Difficulty stars, best times and progress tracking PLAYS ANYWHERE No account, no sign-up, no nonsense. Your progress stays on your device. FAIR & TRANSPARENT Free players get the first four kingdom packs plus six free bonus packs with an occasional ad break. One purchase removes ad breaks and opens every kingdom pack. Hints and bonus packs are earned by choice; rewarded ads are always optional and always your call. Can you crown them all?
