Each player takes his turn to complete a round. At the end of each round, the player with the most count chips wins the round. The winner of the round collects all cards placed during the round and places these cards at the bottom of his pack. If at the end of a round, two or more players have the same number of count chips there is a war. The player with the largest number on his face-up card wins all of the cards in the war.
Rounds continue until time planned for the game runs out or a player runs out of cards.
The player with the most cards wins. Card Design Re-Production Reproduce Divisibility War by copying the numbers listed in the Divisibility War Key onto blank 3x5 index cards as pictured above. My first idea was to create a rummy class game with numbers divisible by a certain number belonging to the same suit. Once I had made a set of cards, I realized that categorizing several three and four digit numbers according to the divisibility rules at one time would require too much of a players memory. This complexity would make a game that is too difficult to be fun.
