some very helpful responses there.

It's triple draw lowball played with 4-card hands, with the distinction
that any hand with four different suits (known as a "padooki")
automatically beats any hand with two or more cards of the same suit -
KsQhTd8c beats 2s3h4d6d.
Aces are low and straights don't matter, so the best hand is A234 of
four different suits.
The one thing that varies from game to game is how to treat a 4-suited
hand with a pair (or two pair or trips). There are three
possibilities:
1. Some people play that it counts as a padooki. KsKcJd3h beats
Ah2h3c5s.
2. Some people play that if no one has a 4-card unpaired padooki then
you compare the best 3-card hands, with 3-suited unpaired hands beating
all other hands. AsAc2d3h beats Ah2h3c5s.
3. Some people play that if no one has a 4-card unpaired padooki, then
you compare hands by standard lowball rankings. KsQsTd8c beats
AsAc2d3h.
