I built a game called Pecos Pete Poker around a couple of decades ago. I recently updated it to play on QB64, and I also got together with TheBOB who offered his graphics playing cards if I wanted to make a graphics version. I've been working on that, and since I love reinventing the wheel, I came up with a completely new poker hand evaluator to go with it. This hand evaluation model is written in SCREEN 0 but can be converted to evaluate graphics hands, which I'll work on next week.
You need jacks or better to display a "Pair" with a payout. Other lesser pairs are marked in grey. Press Enter or any non-number key to draw the next hand. Since it takes awhile to get hands like 4 of a kind, and especially a royal flush, I put number buttons in a menu. Press 1 to wait on a royal flush, 2 for a straight flush, 3 for 4 of a kind, 4 for a full house, etc. Press esc if you get tired of waiting, it will go back to one at a time display.
