PYM Lab — Endless Colour Sort Puzzle

About the game

PYM Lab is a free endless colour sorting puzzle set in a space lab. Each level gives you tubes of mixed colours; pour them between tubes until every tube holds one colour. Level 1 starts with three colours, one more is added every two levels up to twelve, and from level 30 you get one spare tube instead of two.

When you are stuck you can shuffle the level for a new board, or add one extra tube per level. Solving within the target number of moves earns three stars, a few more moves earn two, and using the extra tube costs a star. Stars raise the points for the level.

Sign in with a free Pouyam account to earn points: every solve is replayed on the server before it counts, and the PYM Lab leaderboard ranks the highest level reached. It runs in the browser on phones and computers, with nothing to install.
