Color Sort
Sort coloured balls into tubes so each tube contains only one colour. A satisfying logic puzzle!
How to play
- Click a tube to pick up its top ball (it highlights in orange).
- Click another tube to place the ball there — same colour only, or empty.
- Use the 2 empty buffer tubes strategically to untangle the colours.
- Win by filling each tube with a single colour from bottom to top.
Click a tube to select the top ball, then click another tube to place it. You can only place a ball on the same colour or into an empty tube. Sort all colours to win!
