|Been playing for a while, but still haven't figure out all the rules. Here's what I know:|
1st turn you split your cards into you hand and your 'keep' pile; you play cards from your hand, and the # of cards in your keep pile determines how many 'drinks' you recover each turn.
2nd and subsequent turns you can play a card from your hand, giving you the face-card-value in points and in 'drinks', or you can use a card from you keep pile which moves it to you hand and removes a number of 'drinks' equal to the remaining # of 'keep' cards (otherwise skipping your turn).
Some turns (IDK what triggers this) are 'skip' turns, were you can click on a card in your hand to either discard it and draw a new one, or move it to your 'keep' pile. IDK why some cards are discarded and some are moved to 'keep'.
Playing the same suit as last time improves you score (usually?); specifically your score becomes the face value of the card played plus 2X the # of cards in the run. You 'drink' count only increases by the face card value, though.
Point of the game is to have the highest score, but each round ends when someone gets drunk (thereby losing a life) and each remaining life is worth 40 points @ the end of the game.
There are other subtleties I'm missing, but I DID find a way to always win. Simply put the 6 smallest cards in your 'keep' pile on the first turn then play w/e you draw until she gets drunk. If playing a card would put you at or over your limit, remove the smallest card from your keep pile instead. You'll win every round, both in terms of score and who gets drunk first.
In between rounds, if you get drunk nothing happens, and if she gets drunk you can remove her clothing (permanently) as you choose. After you win the game, if you navigate the moon-rune dialogue choices right (basically anything but bottom, bottom) you get to watch her pee (uh, yeah...) and maybe finger her afterwards. Huzzah.
