I got a deck of playing cards last Christmas, and for some reason I also have a book full of card games. But you know what’s better than playing card games? Making it up as you go along until an idea forms! So here’s one of my games: Dungeons & Treasure! This can probably be multiplayer, but I’ve only tried singleplayer.
Use a deck of 52 playing cards, without jokers. Shuffle it. Without knowing what the cards are, draw two cards face-down, one on top of the other, onto the table. Do the same again, placing these cards beside the first cards. Repeat until you have a grid of 4 by 3 cards. Draw 3 cards for yourself, which you may look at. These 3 cards are your manpower. Now the game begins.
Reveal the top card of any pile. If you have a card of same (to the pile’s card) or higher value (aces are low but are treated as higher against kings) or two cards of the same (to each other) value, you may sacrifice that(/those) card(s) to destroy that top card (sacrificing and destroying cards puts them in the graveyard) and reveal the card underneath. You can either repeat the process or take this bottom card for manpower. If you destroy this bottom card, you draw 3 cards from the deck, these 3 cards being added to your treasure. Treasure can be used as sacrifices just like manpower, but treasure is all that matters when you’re done.
If you cannot (or choose not to) destroy the top card, simply leave the top card face-up and start the process again with a pile that’s all face-down. Once only piles with face-up top cards are left, you may start the processes again with those piles. If the deck runs out, the game ends. If no piles are left, the game ends. If you cannot do anything more, the game ends. At the end of the game, add the values of all of your treasure to discover your total treasure. That’s your score.
I don’t know any neat strategies or odd side-effects or strange consequences or anything, so feel free to give feedback and point anything out.
