Uncertainty didn't kill the cat, but that doesn't mean it's not dead. Dr. Erwin Schrödinger and Werner Heisenberg taught us that. We've all heard about the cats in boxes experiment, and maybe we're even curious about the results - but attempting such an experiment would be INSANE in real life! Now you can try your hand at challenging the uncertainty principle without risking the lives of innocent kittens or exposure to radioactive particles! Awww! In Schrödinger's Cats, players run experiments, form hypotheses, and try to one-up each other's research. Players take on the role of a cat physicist such as Albert Felinestein, Sally Prride, or Neil deGrasse Tabby. Using their special ability to help prove their hypothesis - or at least debunk someone else's - each cat physicist tries to determine the minimum number of alive cats, dead cats, or empty boxes across all the boxes in Schrödinger's lab. In more detail, each player starts with six cards in hand, along with a physicist card. The first player asserts how many identical cards - whether live cat, dead cat, or empty box - are present among all the cards in play. The next player can increase the number of this claim or call. Each player can use their ability once during the round. When a player does call, whoever was right - whether about the claim or about doubting that claim - stays in the game, while the other player is eliminated. Each remaining player gets a new hand with one fewer card, and you keep playing rounds until only one player remains.

To learn the rules, start with "Schrödinger's Cats Example of Play Kickstarter" by Chris O'Neill (9th Level Games), which runs 5 min.
For an opinion before you buy, start with "Schrodinger's Cats Review" by BeardsandBoardgames. To see it played, watch "Schrödinger's Cats - playthrough (3p)" by Board Game Gumbo (Board Game Gumbo).
If you like it, try Dreams of Yesterday and Pavlov's Dogs, also by Heather O'Neill, or Perudo and Cockroach Poker, which share several of its mechanics.
