Do you like to stack cards when playing UNO?

I like to stack and my friend Justin does too.

When you play a draw 1 (or 2) and if another person plays a draw 1 (or 2), you make that person draw 2 (or 4)!

Same when if you play a draw 4 (or 5) and if another person plays a draw 4 (or 5) the next player will have to draw 8 (or 10) or even 12 (or 15)!

I also like doing the train where you can play cards like 2,3,4, and what not.

I created a Python program called Extended UNO. It has cards from a whole bunch of games, including many UNO variations, Skip-Bo, Phase 10, your standard 52-card deck (typical numbered cards), Rack-O (no color, but each digit functions separately), Set (three colors, number is always 1-3), some (but not all) from Monopoly Deal, and a whole bunch more. Fortunately, the game tells you what cards you can and cannot play, but even I sometimes think there's a bug in the program, such as not realizing a Skip-Bo 3 (which is purple) is valid on a Wild DOS with a different color called (it's legal because the Wild DOS is a 2 and Skip-Bo cards are played on cards that are one lower). And there still a few bugs, mostly involving multiple extra turns (some extra turns are required, and some are optional) and effect-when-drawn cards (there are only two, but it gets complicated when something happens in the middle of a turn). I haven't implemented challenges yet (cards that could be challenged simply can't be played to begin with) or countering counters (in the program, if a Draw 4 or similar is blocked, that's the end of it), nor have I implemented scoring (it's one round and that's it, although I do explain how scoring would work for the more unusual cards).

I would post the code here, but it's 60 KB, too long for a forum post.
