The Library lets you choose a puzzle family and browse its puzzles. Try a different family, practise a familiar one or replay a completed puzzle. Each puzzle includes its rules in the game.
Fill every space with a circle or diamond. Balance the symbols in each row and column, avoid three matching symbols in a row, and follow the bars and crosses between neighbours.
Divide the board into rectangles with no gaps or overlaps. Each rectangle contains exactly one clue, which gives its area, shape or both. Match the clue’s shape; a round clue allows any rectangle.
Draw one path through every space exactly once. Start at 1, visit the numbered checkpoints in order, and move horizontally or vertically without crossing walls.
Place lights to brighten every open space. Lights shine along rows and columns until a wall stops them and cannot shine on one another. Numbered walls tell you how many lights touch them.
Place one flower in each row, column and coloured region. Flowers cannot touch, even at the corners.
Join matching pairs with continuous ribbons. Move horizontally or vertically, cover every space, and keep the ribbons from crossing or overlapping.
Connect numbered islands with horizontal or vertical bridges. Use at most two between a pair, match every island’s count, avoid crossings and connect all islands in one network.
Fill a 6×6 board with 1–6. Every row, column and box of three cells across by two down must contain each number exactly once. Starting numbers stay fixed.
