It's definitely more colorful than a rusty trombone. Really, I thought I wouldn't like it at first either. Seemed too weird. But then I tried it and it kinda grew on me.
It's like A-5 lowball with three draws. However, it's played with four hole cards, and with the additional stipulation that your low hand must be comprised of all unique suits.
Your best hands are always four cards, one of each suit, called a "badugi." The nuts is A
2
3
4
, with no preference for the specific arrangement of the suits. Then A
2
3
5
, A
2
4
5
, and so on.
Next down the line, A
2
3
4
plays as a three-card low, A
2
3
, same as if you were to have A
2
3
3
, for example. You can also play two- and one-card lows, but they're unlikely to mean much at showdown.
