I used to practically live at Jai Alai when they had it here in Tampa. It is mostly a numbers game where the odds of certain numbers hitting are very relevant to their post position. Here's how it goes in case someone has never been, usually it takes 7 points to win the game and they play in order. The board starts out....
1- 0
2- 0
3- 0
4- 0
5- 0
6- 0
7- 0
8- 0
#1 plays #2 in the first game, if #1 wins then he gets one point and #2 goes to the bottom. The board would then look like....
1- 1
3- 0
4- 0
5- 0
6- 0
7- 0
8- 0
2- 0
#1 then plays #3, the next one up. As long as you win you keep going. After you go through once then the next round the points count as 2 each. Usually it doesn't go very long after that. Once a man gets 7 points than the game is over and the betting pools are paid due to how many points they have. For instance if the board looked like this...
7- 7
5- 3
3- 0
2- 6
4- 1
8- 0
1- 2
6- 0
The win money would be on 7 since he got to 7 points first. The place would be 2 (6 points), the show would be 5 (3 points). The trifecta would be 7-2-5. If two numbers are tied in points they will have a play-off to determine the winner, those are hard on the heart.
Because the way the game is played certain numerical combinations are very rare. You can go all season and not see an 8-7-6 trifecta. If you do see one it will pay quite nicely.
Back when I went they said about 90% of the players who were professionals all come from a small town in Spain (Basque?) that was known for Jai-Alai. Anyway there will be a test on Monday....
