Uno Dominos

From BoardGameGeek.com:

UNO Dominos for 2 to 6 players ages 7 and up

SUMMARY OF PLAY
Each player draws 6 Domos. The player with the highest starting double goes first. After the starting doublet is placed on the table, each player in turn tries to match by color, number or word. The words on the Domos add excitement to the game by reversing the direction of play, skipping the next player or instruction the next player to draw a certain number of additional Domos. The first player to get rid of his Domos is the winner.

MATCHING DOMOS
In general, Domos are matched by UNO rules and arranged DOMINO style. Match by color, number, or word. But play is limited to the 4 directions of play from the starting doublet. When playing the MATCHING SIDE always constitutes the play. If someone puts down a draw two card and you have one you can put it down.

If at any time you are unable to match color, number or word, you MUST draw ONE Domo from the remaining stock. If the drawn Domo is playable, you may play it immediately. If it is unplayable, it is added to your hand and play passes to the left to the next player.
