Brain training inside a cube: colors, constraints, and crowns waiting to be found. Step onto a three-dimensional board made of colored blocks; your goal is to discover all the hidden crowns. Every move follows three strict rules: one crown per row and column, one crown per color region, and crowns may not touch each other (including diagonally). Tap to place crowns and mark impossible spots with an X — logical deduction gives immediate, visual feedback at every step. Controls and visuals: rotate the view to inspect the 3D structure more easily; Responsive touch controls, with undo and hints to help you rethink without starting over. A fresh color palette and elegant block-and-crown designs make searching a pleasure. You'll appreciate the details: the pace suits quick plays during short breaks while also inviting deeper focus for tougher puzzles; each level has a clear objective, visible progress, and victories that deliver a calm, satisfying sense of accomplishment. The sense of achievement comes from that moment of insight when conflicting options fall into place, not from a pure speed contest. Treat each solve as a short mental tune-up—start relaxed and enjoy the satisfaction of the next solved puzzle. ## Key features - 3D cube logic puzzles - Color and region constraints - Crown placement rules - Visual feedback - 3D rotation controls - Undo and hint system ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/crowndoku-logic-puzzle-master/id6791945528/reviews.md ### 5/5 — Queenパズルの立体版 *2026-08-20* 一問につき盤面が6面あるので、良く言えば解きがいがあるけど、悪く言えば見通しづらい。あと、連続バツ印が長押しからのドラッグなので、慣れが必要か。でもQueenを色んな動物に変えただけのクローンアプリよりは見た目にリッチだし、楽しい。 できれば、GameCenterログインかAppleログインで複数デバイス間セーブデータ共有ができると嬉しい。 ### 5/5 — It’s Simple, so I love it *2026-08-18* 1 Crown for every X, Y, and Z axis, and Crowns Can’t Touch At All. 1+ Crowns for every ring of the levels, which themselves are 3D(3-Dimensional) “Squares and Rectangles). Sounds Simple. I love it. The graphics are, well, wonderful, and the game itself is Very Easy/Enjoyable. Please make a part 2 and 3 ### 1/5 — No Taps! *2026-08-15* The game is interesting but I’m finding it almost impossible to place a crown. I try over and over, fifteen, twenty times, before the crown finally appears. I haven’t had this problem in any other game. Finally deleted it in frustration. Too bad. ## Frequently asked questions about Crowndoku ### What is Crowndoku?
