Puzzle games

These free puzzle games for kids, families and classrooms open right in your browser. There's nothing to download, no sign-up and no chat, and they work on phones, tablets, computers and school Chromebooks. Each one is short enough for a break and has enough to think about to come back to.

Arcade Memory Match is the gentlest place to start. Flip two cards at a time to find matching pairs of arcade icons. Every icon has its own shape as well as its own color, the boards grow from 12 cards to 30, and there's no timer and no way to lose.

Mirror Light Puzzle is about light and color. Turn mirrors to steer red, green and blue beams onto seedlings, and mix the light so each one gets exactly the color it wants. Every color also has its own pattern, so you don't need to tell colors apart to play, and there's a new daily puzzle every day.

Dot Code Breaker is a code-breaking puzzle. Draw a path through a grid of nine dots, and use the marks each try leaves to work out the secret path. Practice mode has no timer and no limit, and it plays fully with a keyboard.

Tidy Tiles Puzzle asks you to clear a small tray in a few moves: arrows push, crosses clear and stars sink into new holes. It plays with a keyboard as well as by touch.

Satisfying Token Sort is a calm sorting game. Drag arcade tokens into the machines that want them and watch parked tokens roll in on their own. The first boards, and every fifth board after them, can't be lost.

No Energy Merge Workshop is a merge puzzle with no energy bar and no waiting. Drag matching parts together to build up to a finished arcade machine, and plan your moves so one merge sets off the next.

Apart from Dot Code Breaker's optional Countdown mode, none of these puzzles has a timer, and each one saves your progress in this browser, so a closed tab costs nothing.
