There used to be a lot of the Sigma Horse Race machines around The Strip and Downtown. Now, only the MGM has one of those machines. I wish that game was availible in more casinos.....it's usually crowded at the one at MGM.. I was told it is hard to get parts for the machine when it needs repairs...how can that be? Someone needs to start making the necessary parts to help bring these machines back......they're a classic, and it's so easy & fun to make friends while betting on each horse race. It's just a quarter a bet, and the machine holds your credits for betting, or drops the winning quarters.....no tickets......just like the goold ole days! If you've never played it, buy a roll of quarters and give it a try.
