-1d20, 1d12, 1d10, 1d8, 1d6, 1d4, and a coin (1d2)
To start, each player rolls the d20 and subtracts five from the result. This determines the players' constitution. It will also determine who goes first.
(Constitution makes it so you're less likely to die from fat.)
Each player places their piece on "Start"
To start, all players roll a d20 and go the number of spaces that it says to go.
If a player lands on a +fatness square, the player must go down one die size.
If a player lands on a liposuction transfer square, they can agree to transfer fat to or from another player, affecting their die sizes accordingly. A player cannot go above 1d20 or below 1d2 for transferring fat.
Every time a player crosses the starting line, they add 1d4 to their constitution.
If a player becomes too fat (example: Jimmy is at 1d2 and lands on a +fatness square), they must make a "saving throw." They take the first digit of their constitution modifier (example: 19 would be 1; 6 would be 6), and add it to 1d20:
8-14: Survival, but the player cannot roll to move next round
If the player rolls a natural 19 or 20: Lose fatness. Go up to 1d6
The player must reach 17 constitution + 1/2 their initial constitution modifier. (example: Jimmie rolled a 14 for his initial constitution modifier, so he will need 24 to win)
