JAI-ALIJ is no different than playing the pick 3 daily lotto to me! 
In the 80's & the early 90's, Jai-Alai in Dania beach and Miami was packed on a Friday and Saturday night. The Latin folks just loved the game. From the basque region of Spain. Best American Jai-Alai star was a guy named Joey Kornblit. And your are right. You just play numbers and hope to hit a nice one.
