WHEN I FIRST STARTED WATCHING JAIALAI AT MGM GRAND IN LAS VEGAS THEY HAD A $5 BET CALLED TWIN EXACTA. IF YOU HIT THE FIRST HALF YOU TRADED IT IN FOR 2ND HALF. THERE WAS NO CARRYOVER AND MANY TIMES ONE NUMBER PAID THE SECOND HALF. THEY DID NOT ANNOUNCE HOW MANY EXCHANGES AND YOU WERE LEFT IN THE DARK. ONE NIGHT I HAD AN EXCHANGE AND SWEATED OUT THE GAME. AFTER THE GAME I FOUND OUT I HAD THE ONLY EXCHANGE AND WAS AN AUTOMATIC WINNER FOR $1500. I NEVER FORGOT THAT.
