Sudoku Hex

Sudoku, built for a hex grid.

Every cell has six neighbors instead of four, and the grid has three straight-line directions instead of two — so alongside the usual rows and columns, a third diagonal axis also has to hold every digit exactly once. It's the same one-answer logic you know, with one more direction to track.

TWO BOARDS
• Sculpted Hexagon — a hand-crafted 7-region flower of hexagons
• Parallelogram — a classic 9×9 hex grid, rotatable between four looks (lean, steep, wide diamond, tall diamond) to fit however you like to hold your screen

FOUR DIFFICULTIES
Easy, Medium, Hard, and Expert — twenty puzzles each, so there's always a fresh one waiting.

DAILY PUZZLE
One shared puzzle a day on each board. Solve it to keep your streak alive and see how your time stacks up on the leaderboard.

PLAY YOUR WAY
• Notes mode for candidate digits
• Undo/redo and a mistake counter
• Logic-based hints that explain why, not just the answer
• Row/column/region highlighting you can turn on or off
• Light, dark, or system theme, with four accent colors
• A black-and-white mode if you'd rather the regions stay plain
