Four - the value of the pile remains the same but the direction of play reverses. Ten - increases or reduces the value of the pile by ten, at the player's choice. King - the value of the pile is set to 99. If you cannot play without taking the value of the pile over 99, you lay down your hand. After each hand, the deal passes to next player to the left of the previous dealer who is still in.
Hands continue till only one player has any pennies left, and that player is the winner.
This game should be played very rapidly. It is easy to forget to draw a replacement after you play a card. If that happens it cannot be corrected afterwards - you must get by with just two cards for the rest of the hand. The number of coins players have at the start of the game can be varied, as can the number of cards in each player's hand. For example Alan Orcutt reports a variation in which everyone starts with 4 nickels and five cards are dealt to each player.
