Overview

Felicity: The Cat in the Sack is a bluffing and auction game. Over 9 rounds, players secretly contribute Pet Cards (cats of varying values, plus rabbits and dogs) face-down to a central row. Players then bid Mice Money to claim the entire “sack” of cards. Passing players collect consolation mice from Mouse Cards. Dogs in the sack chase cats away. The player with the most points (cat values + remaining mice) wins.

Components

Setup

For 4-5 players:

  1. Each player takes 1 set of 10 Pet Cards in their color.
  2. Each player randomly draws 1 Pet Card from the player to their right and discards it unseen to the box (so each player has 9 cards).
  3. Each player takes 15 Mice Money (1x5 + 10x1).
  4. Create a bank: 33 mice for 5 players, 27 mice for 4 players. Return excess to box.
  5. Lay out Mouse Cards in numerical order. For 4 players, remove the “3” Mouse Card.
  6. Place the Cat in the Sack Card to the left of the lowest Mouse Card.
  7. Place Mice Money from the bank on each Mouse Card equal to its value (e.g., 6 mice on the “6” card).
  8. Choose a starting player.

For 3 players: Use only the “3” and “6” Mouse Cards. Bank = 21 mice. Add a 4th dummy player’s shuffled set face-down (1 card removed unseen).

Turn Structure

Each of the 9 rounds:

1. Card Selection

Starting with the start player and going clockwise, each player places 1 Pet Card face-down in a row. The start player’s card goes under the Cat in the Sack Card; subsequent cards are placed to the right under the Mouse Cards.

2. Auction

3. Passing and Revealing

4. Winning the Auction

5. Cleanup

Refill Mouse Cards with Mice Money from the bank equal to each card’s value. Begin the next round.
