Fourwind Mosaic
Slide eight colored dominoes into a 4×4 mosaic from any of four winds. Choose an entry edge, then tap a cell in the row (West/East) or column (North/South) you want to use. The domino slides until another tile stops it. Its two colors are printed in entry-to-interior order: changing to the opposite wind reverses their physical order. Match the faint A/B blueprint in every cell after all eight pieces. A wrong color is not repaired by later tiles, so plan which gaps must be filled from which edge. Undo removes your last insertion and restores the queue. The fifth row/column are border markers, not playable cells.
