Tubes
Sort the balls so each tube holds a single color.
How to play
Tap a tube to lift its top ball, then tap another tube to drop it there. Keys: ← → and Space, or 1–9 for a tube. R rewinds, P pauses.
Rules and score
A tube holds 4 balls. A ball can go onto the same color or into an empty tube. Each ball you move uses one move. When every tube is empty or holds four of one color, the rack is sorted: you score its balls (colors × 4) and get moves for the next rack. The first rack has 3 colors in 5 tubes, growing up to 7 colors, always with two spare tubes. If your moves run out first, the game ends.
Tips
- Keep one empty tube free as long as you can.
- Finish a tube that is almost one color first; then you can forget it.
- Before you move, look at what's under that ball. Choose moves that open up the next one.
- Stuck? Rewind the rack to its start. Used moves stay used.
FAQ
- What if no move is left?
- After a moment the rack rewinds itself. Every rack is shuffled so it can be sorted within your moves.
- What if I stop for a while?
- After 20 seconds without a move, the clock stops and the game pauses itself.
