Short description of Dominoes For Windows 5.2: The fun & addicting game of Dominoes. You get the two most popular games in the US & the UK, Sniff and Fives & Threes. With Sniff you drag and drop bones and score when the ends total a multiple of 5. If you can' t make a play you draw from the bone pile until you can. With Fives & Threes you score when the ends total a multiple of 5 or 3. To make things more challenging there is no bone pile to bail you out and you must " peg out" exactly.
