A secondary challenge was to make it down so that it will print on a single page of paper. Then the third challenge was to make the rules fit on the back of a business card. I think I did both. The rules below will fit onto the back of my business cards and remain legible.
The object of the game is to knock out the other player's boxers
Each player needs a deck of 30 business cards with a name and telephone number. Each player shuffles his/her deck and draws 5 cards. These are the player's boxers. The player lays them down in the order he wants them to fight. Each player then draws 5 more cards as his hand; these are his action cards.
Use most upper left phone number and ignore any area codes. As a boxer the first digit is the Left Punch and the last digit is the Right Punch. As an action card, only the first 3 digits of the number are used. 1-3 is Left Punch, 4-6 is Dodge, 7-9 is Right Punch. 0 does Nothing. The HP of each boxer is 10 plus the amount of letters in the first name. Punches land if they are played against an opposite Punch or a 0. Punches don’t land against a Dodge or the same Punch, e.g. two Rights.
Each player has his/her 5 boxers set and has a hand of 5 cards. The first match begins with players playing cards from their hands. They compare the action card results with each other. Each boxer takes hits according to what his opponent does for damage. When a boxer has 0 or fewer HP s/he is out and the new boxer steps in to take his/her place. The winning boxer remains with the same HP. This continues until one player has lost all his/her boxers or players run out of cards to draw. The winner is the player with the most HP left on his boxers.
Players play their action cards, 479 vs 182. The first digit shows players’ Dodge and Left, the next is Right and Right, followed by a Right and Left. The first one is missed because a player Dodged it. The second is canceled because they both went right and the last one both hit because they went opposite. Player 1 deals 9 points and player 2 deals 2 points of damage.
I think it's playable. I haven't tried it yet though. Let me know if the rules don't make sense. It was difficult to make it fit on the card and still provide enough information.
Try it out at your next convention or if you happen to have a stack of business cards lying around. I'd love to hear what people think of it.
Play games. Always.
