Badugi is a very simple game, you get 4 cards, you get to draw as many as you want 3 times, and then there is a showdown. Whoever has the lowest hand of 4 different suits, unpaired, wins. So if you have 9 of clubs, 8 of hearts, 3 of diamonds, 2 of spades, you have a 9832 low badugi. However, you would lose if someone has a lower number, for example, 7 of hearts, 6 of clubs, 5 of spades, 4 of diamonds, because 7654 is a lower number than 9832, even though your lowest card is lower, the ranking is counting from the top down. If nobody has a qualifying badugi, it goes to the best 3 card hand. So, for example, if you has 2 of spades, 3 of clubs, 4 of diamonds, and a 4 of hearts, you only have a 3 card ranking hand of 432. But you would still win vs an opponent with something like 8 of diamonds, 7 of diamonds, 6 of spades, 3 of clubs. His ranking would be a 3 card hand of, 763.

2-7 is also simple, you get 5 cards, you get to draw 3 times or 1 time, depending on the version, and it is just the opposite of normal poker rankings. So, in normal poker, the best hand you can have is a royal flush. Well, that's the WORST hand you can have in 2-7. The best possible hand in 2-7 is 75432, as long as they aren't all the same suit, because that would be a flush. So, for example, in 2-7, if you have 76522, a pair of 2s, you would still win if your opponent had 88543, which would be a pair of 8s. Also ace is high only in this version. So you having K7652 would win vs someone with A6543. Because ace is higher and the winner is the one with the lower hand.
