It's indeed fun to play , and alllott of bluffing going around in it, the id is to get the lowest hand possible with 4 different suits
so if you got A

2

3

4

you got the nuts , almost like razz but with razz you get 7 cards in a row, this is like 5 card draw rules , you can discard the card you dont like to get a new card, and you may discard multiple cards as you wish , but only in 3 betting rounds ..
And you cant have A

A

2

3

then you havent made a complete hand even if the suits are different you will need to have 4 different cards aswell , the chance of winning is not that huge , but thats why the bluffing comes into play
