We found a game at Sienna, in Reno, called Capistrano that was quite entertaining. It has 4 separate games, which normally means at least a $1 per spin bet. But this is $.50 for play on all 4 games. My wife and I both played it and we were both up a bit. the game has a lot of potential because if you get a full set of wilds, then these "roll over" to the rest of the games. So if you get a full set of wilds on the first game then the other 3 games will also get that same set of wilds. Numerous times we had multiple rollovers which netted some good payouts. since the total bet is $.50, then really you are only playing $.125 a game. So it is affordable.
The game has the theme of the swallow at Capistrano in CA. Anyway, we have not seen this game anywhere else but we both liked it.
Give it a shot if you see it at your local casino.
