How Ponder works
Everything is free and runs in your browser. Here are the ways to play.
Daily set
Six puzzles a day from six of the eight families. Take them slowly in Calm, or Race through them on one clock and compare times with friends. Choosing Calm sits you out of that day’s Race.
See today’s setWeekly collection
Forty-eight puzzles: two at each difficulty from every family. Take the whole week, focus on one family, or dip in whenever you like.
Open the Weekly collectionLibrary
Pick a family and a difficulty and open any board. It’s the easiest place to learn a new set of rules, and you can replay anything you’ve finished.
Open the LibraryHints and accounts
Every board comes with its rules and a hint that shows a next step or spots a mistake. You don’t need an account to play; one adds Race, friends and groups.
Compare ways to playEight kinds of puzzle
Each has its own rules and its own kind of thinking. Read a guide, then try a board.
Binary
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.Read the guide
Rectangles
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.Read the guide
Paths
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.Read the guide
Light Up
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.Read the guide
Blooms
Place one flower in each row, column and coloured region. Flowers cannot touch, even at the corners.Read the guide
Ribbons
Join matching pairs with continuous ribbons. Move horizontally or vertically, cover every space, and keep the ribbons from crossing or overlapping.Read the guide
Bridges
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.Read the guide
Mini Sudoku
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.Read the guideWork through a puzzle
