Einfach tierisch!

No — you cannot pick up cards you have already played; you may only increase your bid by adding new money cards to the ones already on the table (page 4).

Yes — if you have already bid and then pass you return all your face-up money cards to your hand, but you may no longer bid that round (page 4).

You are bidding to avoid taking the disgrace: the round ends as soon as any one player passes, that passing player picks up their money cards and must take the disgrace, while all other players discard their money cards face-down; the passing player starts the next round (page 5).

If you take the Faux Pas you must immediately discard one luxury card you have in front of you (or the next luxury you receive if you have none), and once a luxury has been discarded the Faux Pas card itself is discarded (page 5).

The game ends immediately when the fourth dark-green card (the three prestige cards and the Scandale) is revealed — there is no bidding for that card — then all players reveal their hands and the player(s) with the least remaining money are cast out and cannot win (page 6).

Add up luxury card values, apply prestige multipliers (each prestige doubles your status; two = ×4, three = ×8) and apply disgrace effects (e.g., Passé −5, Scandale halves status); the highest status among players not cast out wins, with ties broken by most money left and then by the single most valuable luxury card (pages 5–6).
