Domino Little Harp

Face-down tiles form a seven-column harp layout, with the stacks rising from one domino in the first pile to seven in the last. Only the lowest tile in each pile shows at first, leaving the rest covered until movement exposes them. Domino Little Harp uses a double-six set, and the round ends only after every piece has been revealed.

How to play?

Move any exposed tile or an exposed run onto another column when the touching ends match. After a transfer leaves a covered piece at the base of that column, flip it face up immediately. In any vacant column, place any single tile or any upward group without restriction. Reveal the full layout to finish the deal.
