I'm gonna have a messy session on my own and I like playing a game or something to ad to the fun which I like to do. Does anyone know any one player games people may have done before?
I usually use card games to do what you're describing.
Start with 15 red cards in five piles with 1, 2, 3, 4, 5 cards. Add one black card to each set, and shuffle each set (2,3,4,5,6 cards) separately.
Lay out the cards in a pyramid with the two cards on the top row, then three on the next row, down to six cards on the bottom row. So, the entire pyramid is red cards with one black card in each row.
For the game, start on the top row and flip over a card. If it's red, suffer the punishment; black, you're safe. After you pick a black card, you progress down to the next row, until you've found all five black cards. You can also add a joker somewhere in the mix for an extra big gunging.
