Mahjong 3D Connect

The rules haven't changed from the mahjong you already know — pick two matching tiles that are both free on the edge of the stack, not boxed in by neighbors on both sides. What's different here is the 3D presentation, which makes judging what's actually exposed a little trickier than it looks on a flat board. Worth a look if you've played the 2D version and want the same puzzle from a different angle.
