Arrange the tiles so that their sides match each other in colors or symbols. Black lines appear when the sides are properly aligned.
More levels are available in the App Store: https://apps.apple.com/us/app/id1555093399
Controls:
Mouse click - rotate tile.
Mouse click and drag - move tile.
Update:
I added symbols to make it easier to distinguish tiles from each other - option available in the menu.
Thanks for playing. :)
