IN THE 70'S MY WIFE AND I STOPPED PLAYING SLOTS AND WENT IN MGM LAS VEGAS TO CHECK IT OUT. OVER 30 YEARS LATER WE ARE STILL HOOKED. THEY HAD A $5.00 BET -CALLED TWIN EXACTA SIMILAR TO BIG Q. IT WAS PAID OUT EVERY NITE. SOME OF MY BIGGEST HITS WAS THIS GAME--ONE TIME I WON THE WHOLE POOL WITH THE ONLY EXCHANGE.
