Death is a board game. It's pretty much the opposite Life. What you do is instead of going home you start home and run away to the grave. Instead of collecting money you collect souls. Contract with soul contracts you can buy things to screw the other people up. You could give people cards that give them longer life such as vegetables or wealth, etc.
In Uno you have to lose cards but in Dos you have to gain cards. You start of with 2 cards. The same rules are if you play a blue card the other person has to play a blue card or the same number but a different color, except the number on your card is the number of cards you gain the highest number card is 3 and instead of the +2 cards its a -2 card. The first person to 25 wins the game. You could make the number whatever you want because who follows rules?
