Only the current version so far — new entries appear as the game ships updates.
Yohaku is a sorting puzzle. Move chips between tubes until each color sits alone.
There is no timer and no move limit. If the board sticks, undo a move, take a hint, or open a locked tube. You can always restart.
Tap a tube to lift the top color. Tap another to set it down. Matching chips move together. An empty tube accepts any color. A filled one accepts only the color on top.
A tube is done when it is full of one color. The level is done when every tube is finished or empty.
Some chips start face down. Move the one above them and the mark appears. Some tubes start locked.
Early boards are plain. Later boards are not.
