Back then the house advantage was just 2.32 per cent, which was unheard of for a game where 40-1 pay-outs can be won. Perhaps the reason it became so popular is the original pay-table for Pair Plus paid 4-1 on a flush. 3 Card Poker was first tested in Las Vegas casinos in late 1999 and is now a popular table game that can be found in virtually every multiple-pit casino in the city.
