Evenfold: Binary Logic Puzzle

Fill the grid with Embers and Tides. Three simple rules, and every puzzle has exactly one solution that you can reach by logic alone.

THE RULES
• Never three in a row: no more than two of the same tile side by side, across or down.
• Split every line evenly: each row and column holds as many Embers as Tides.
• No twin lines: no two rows, and no two columns, are the same.

A NEW DAILY PUZZLE
Everyone gets the same grid each day. Solve it to grow your streak. Puzzles are gentle early in the week and tougher at the weekend.

ENDLESS PUZZLES
Pick 6×6, 8×8 or 10×10, and Easy, Medium or Hard. Every grid is freshly made on your device, so you never run out.

HINTS THAT TEACH
Stuck? A hint doesn't just fill a cell. It shows you which tiles to look at and explains why the move works, so you learn the tricks as you play.

MADE FOR FOCUS
• Mistakes are highlighted as you go (you can turn this off)
• Undo, restart and a timer that pauses when you leave
• Your game is saved automatically
• Stats for best and average times
• Light and dark themes
• Tiles differ in shape and colour, so they're clear for colour-blind players
• Works offline
