How to play

Sort the coloured liquids so every test tube holds a single colour. Tap a tube to pick it up, then tap another to pour. You can only pour onto the same colour or into an empty tube.

Common questions

Lost a purchase? Open Settings and tap Restore.

How do lives work? Restarting or leaving a level after you have poured costs a life. Lives refill one every 30 minutes, up to 5.

What is the Daily Lab? One puzzle per day, the same for everyone. Your fastest solve goes on the leaderboard. You get 3 tries per day.

What do the frozen and locked tubes do? A frozen tube thaws after the number of pours shown on it. A locked tube opens once you finish a full tube of its key colour.
