Crowndoku: Queens Logic Puzzle

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.
