Einer geht noch! (a.k.a. Cruise or Lose) is a family card game that lets players send their animals aboard boats that will not capsize as long as their very strict weight limits are adhered to.
You draw three animal cards per round. You play these into boats: twice face up and one time face down. Each boat holds only three animals, though. After all of them have boarded, some animals can cause others to switch boats. Any boat with passengers that, in total, are too heavy for it will sink. Animals aboard boats that don't sink are worth VPs. If you have the most VPs after four rounds, you win.
