An abstract and very simple pen-and-paper game that simulates the back and forth deadlock of the war of trenches, created by Alejandro Grilli J. (agj) for the Level 3 WWI challenge.

Players: 2

Preparation:

• Write down a random sequence of digits, more than 6. Repeat it for your opponent.

Player A: 65583205124

Player B: 65583205124

How to play:

• Players take turns picking any amount of digits from their list, and stringing them into a single number. They write down this number and cross the digits from their list.
• The first player may write any number. For each successive turn, the players must write down a number that is higher than the previously annotated one.

End of the game:

• The player who does not have the digits required to form a number higher than the previously played one loses to his opponent.
