About Kernel Sort

Glass tubes hold stacks of coloured kernels. Tapping a tube picks up the run of same coloured kernels at its top, and tapping another tube pours them in when the colour matches and there is room.

Every puzzle can be finished: two tubes start empty, four kernels of each colour are dealt, and a dealt puzzle is only used once a solving search confirms that a full answer exists.
