Flipping Pennies

A children's game in which the two players each flip pennies, or some other coin, at the same time. The players take turns calling "odd" or "even", then both players reveal their coin simultaneously. Heads/Tails or Tails/Heads is odd Heads/Heads or Tails/Tails is even. This isn't much of a game, and there are ways to cheat!! But if done fairly it is a perfect example of an "Dice Rolling". The coins are randomizers. d2 or d6 doesn't matter! So the game would play just the same if the two players rolled d6 dice and noted if the sum of the dice was "Odd or Even." Since this is a gambling game too, the players would have to each bet a stake of 1 penny.
