HexDoku
Hex Puzzle Brain Teasers
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Master 55,260 pure-logic puzzles across three magical realms. Learn with reasoned hints, build streaks, earn achievements, and climb the Game Center leaderboard.
Discover a fresh kind of logic puzzle: place crystals across a hexagonal grid and solve every board by pure deduction—never guessing.
Inspired by the satisfying constraints of Sudoku, HexDoku uses a completely different board and four simple rules:
• Place exactly one crystal in every ascending lane.
• Place exactly one crystal in every descending lane.
• Place exactly one crystal in each color region.
• Keep crystals from touching neighboring hexes.
Mark impossible spaces with Xs, follow the crossing lanes, and watch each deduction open the next move. There is no arithmetic, and every puzzle has a unique solution.
