Three Card Poker is actually pretty straightforward! You start by placing an Ante bet, then you get 3 cards and the dealer gets 3 cards. After looking at your hand, you decide whether to fold (lose your ante) or place a Play bet equal to your Ante. The dealer needs Queen-high or better to qualify. If dealer doesn’t qualify, you win even money on your Ante and your Play bet pushes. If dealer qualifies and you win, you get paid even money on both bets. Basic strategy is to play with Q-6-4 or better, fold anything worse. There’s also optional side bets like Pair Plus that pay based on your hand strength regardless of dealer’s hand. I’ve been playing at Grosvenor Casino online and their RTP is around 97.99% for the main game, which isn’t bad compared to other casino games
