Two unique tokens for each player (can be anything; coins, keys, jelly beans, etc. just make sure it’s clear each player knows which tokens are theirs as they will hold onto them throughout the game)
Reward tokens (to be paid out by the banker for correct wagers; can be poker chips, money, candy, etc.)
Everyone starts off with:
An index card (or similar) on which to write their answer and a pen
Two unique tokens that stay with you through the whole game
Assign someone to be the question reader and someone to be the banker
Both can still play
How to Play
Question reader reads the question aloud, and everyone writes their best guess on their card
After your answer is written, place it face-down on the table
Once everyone’s cards are in, the question reader flips the cards over and arranges everyone’s answers in order from smallest to largest
If two people guess the same answer on their cards, the two cards are considered the same and simply stacked together.
Odds are assigned to answers based on their spot in the order
For odd numbers of unique answers: The answer in the middle has odds of 2:1, the next two cards out from the middle have odds of 3:1, the next two out have odds of 4:1, and so on.
For even numbers of unique answers: The two answers that are in the middle have odds of 3:1, the next to are 4:1, and so on.
Once everyone’s cards are arranged and odds are assigned, players wager their unique tokens on the guess they think is closest without going over the correct answer. You can place all your bets on one answer or you can split the tokens you wish to wager between two (and only two) different answers.
For example: If the question was about a year in which something happened and the guesses were 1940, 1946, 1950, 1952, and 1960, and the correct answer was 1959, 1952 would be the winning answer since 1960 went over the correct answer. Any wagers placed on 1952 would receive 3 tokens per token wagered since that guess’ odds were 3:1.
Technically 1960 is closer and would seem to be the winning bet, but because it went over the correct answer, it loses. Were the correct answer a year after 1960, like 1990, any wagers placed on 1960 would be considered the winners and be paid 4:1 for each token wagered. This is to avoid ties that would inevitably occur.
If you wish to wager your tokens on anything smaller than the smallest answer, you may do so and the odds are one greater than your greatest odds (6:1 if the cards on the outside of the answers are 5:1). For example, if the answer from the previous example were 1939 and everyone’s bets were placed on the various answers and not on the “smaller” option, nobody would win.
Once the winning answer is determined, the banker collects all tokens wagered on incorrect answers and returns them to the bank. Players get to keep their two unique tokens so they have something to wager the next round. Any tokens placed on the correct answer receive their reward tokens from the banker, based on the odds.
For example, if you bet 4 tokens (one of your unique tokens, and three reward tokens) on the correct answer that pays out 3:1, you would get those four tokens back as well as 12 new reward tokens. If your other unique token was placed on an incorrect guess, you still get that back, but all reward tokens placed on incorrect answers are lost.
Winning the game: You can either set a predetermined number of questions or reward tokens to determine who won, or you can play as long as you’d like, it’s up to you. But, whoever has the most tokens at the end of the game wins.
