Composition

Composition is a daily puzzle from Babs Technologies, played in the browser at playcomposition.com and in an iPhone and iPad app released in October 2026. The canvas holds a number of black dots that bounce around without stopping. You swipe across it to draw a straight line, which grows out from where you started. If a dot hits the line before it is finished, the line breaks; once it reaches the edges, it stays.

Every space you close off with no dot inside fills with paint. Paint three quarters of the canvas and the board is done, and what is left is a painting of black lines and planes of colour in the manner of Piet Mondrian. Finished canvases hang in a gallery in the app, each named after its colours, biggest first, the way Mondrian titled many of his works.

The daily board is numbered and dated, and it is the same for everyone in the world. It changes at midnight UTC. You get three tries, and the clock only starts with your first line. Difficulty follows the week: Monday is the gentlest, the boards build to Saturday, and Sunday is calm again. Each board lists its dots, the walls already drawn and how many spare lines you have, and a hint is there if you want one. Since the app update of 19 October, a pause covers the canvas until you come back, so pausing no longer costs your place on the leaderboard.

In the app you race the friend just ahead of you on today's board, or your own best, or the fastest time in the world, and their lines appear over yours in pencil when you finish. There is also a mode for two or three people to paint one canvas together, on one phone passed around or on their own phones. Today's board is free every day; a single purchase adds every past board and 45 more Studies, the game's practice levels. There are no ads and no account to make, and the daily board and the Studies work offline in the app.

It suits players who like a short test of timing and nerve more than a word or number puzzle, and anyone who enjoys ending the day's game with a small picture to keep.
