Another Gem ;). It takes about 3 seconds to teach and has almost everyone sweating on their turn trying to figure out how to match these 2d/3d cubes on the play area.
It's simple, take you asymmetrical cubes with coloured gems to match to any visible gem on the board. You can play next to or ontop of existing cubes, but all touching gems must align colour to colour or any colour to black.
In order to play a card, players must have enough physical gems in the matching colour. Make a match, you get to discard your gems to the score board. The goal, to eliminate all your gems.
If you would ever score more gems then can be place on the gem board, you can 'gift' the overflow to another player adding additional negatives to their score.
It's pretty, light, fun and fast to teach/set up with enough puzzle to bit into.
