Gridhaiku

Five small logic puzzles a day.

A calm daily ritual of hand-made grids, from an easy Monday to an expert Sunday. Every grid has exactly one solution, and logic alone gets you there.

• Number PathDraw one path from 1 through every cell.
• RectanglesSplit the grid into rectangles, one number each.
• IslandsConnect every island with the right number of bridges.
• BinaryFill every cell with a sun or a moon, evenly in every line.
• Star BattleOne star in every row, column and region.

Keep a streak, earn freezes for the days you miss, and play as many extra grids as you like in Unlimited.
