Tint Tubes: a free color sort puzzle

Tint Tubes is a relaxing color sorting game you can play right in your browser. Each level gives you a set of tubes filled with mixed colored balls. Move the balls between tubes until every tube holds four balls of one color. There's no timer and no download, and new levels keep coming.

How to play

1. Tap a tube to pick it up. Its top ball (or stack of same-colored balls) is ready to move.
2. Tap another tube to pour. A ball can only land on an empty tube or on a ball of the same color.
3. Each tube holds four balls. If the target has less room, only what fits is moved.
4. The level is solved when every tube is either empty or full of a single color.

Tips for harder levels

• Keep an empty tube free as long as you can. It's your most valuable space.
• Look a few moves ahead. Before you fill an empty tube, check which color you can stack on top of it next.
• Finish nearly-complete tubes first. A tube with three matching balls only needs one more.
• Stuck? Use Undo freely, ask for a Hint, or add one extra tube per level.

Controls

Works with touch and mouse. On a keyboard, press 1–9 to pick tubes, Z to undo, H for a hint and R to restart. Turn on colorblind symbols with the shapes button at the top.
