Standard 9/6 Jacks or Better video poker
Controls should hopefully be straightforward (directional buttons and primary action button, e.g. Z), with the following notes:
-Press up to scroll up to the pay table above the play area.
-Secret quick-draw feature: After holding, you may press the secondary action button (e.g. X) to instantly "draw"
Note: This game makes use of audio/video synchronization (particularly in the intro) that seems to not work very well on the web version (on my computer at least; maybe you will have better results) and it looks/sounds way better if you run it in the native PICO-8 client.
Good luck :)
EDIT 2015-06-11: Updated for PICO-8 0.1.1 compatibility
EDIT 2017-06-16: Fixed coin-count display bug, adjusted several sfx volumes to avoid distortion
EDIT 2018-04-10: Added support for some things that did not exist in PICO-8 when I first made this: saving to cartdata (and "cash out" menu option to reset), button glyph on title screen
