Rules!

Welcome to the Odd or Even game!

The objective of the game is to correctly guess whether the total number of marbles is odd or even.

Here's how the game works:

• Both you and your opponent start with 10 marbles each.
• On each turn, the guesser will wager a number of marbles and the hider hides an amount of marbles.
• The guesser has to guess if the total number of marbles that the hider is hiding is odd or even.
• For balance sake both the player and the computer can only wager or hide a maximum of 4 marbles.
• If the guesser guesses correctly, the hider gives the amount of marbles wagered to the guesser.
• If the guesser guesses incorrectly, the guesser gives the amount of marbles wagered to the hider.
• The game continues until the player has lost or won all the marbles.

If the rules aren't clear you can always check out the role button in the top left corner.

You are the Guesser!

• You declare if you think that the total marbles the computer is hiding is odd or even.
• You declare how many marbles you want to wager up to a maximum of 4 marbles.
• After you declared your decisions the computer has to show his hand.
• If you guessed odd or even correctly you win the amount you wagered and take it from your opponent's marbles.
• If you guessed odd or even incorrectly you give the amount of marbles wagered to your opponent.
• Afterwards the roles switch.
