Same One!

In the basic rules of Same One!, you're trying to dump your cards as quickly as you can, and whoever goes out first wins. The deck consists of 90 cards, numbered 1-30 in three colors. Cards 1-15 have up arrows while 16-30 have down arrows, and the most recent card played dictates whether the next card must be higher or lower. If you have more than one card of the same number, you can play them together. If you can't play a card, you draw a card, then play it if possible. The rules for Same One! include four variants, and you can use one or more of them as you choose. In the simplest, you can't go out with a shark card (i.e. #13-18) on your final turn. Another variant requires that you match the color of the card last played, with sets of more than one number allowing you to change the required color. Another variant has you playing multiple rounds and tracking the points won or lost by each player. When someone goes out, each other player loses as many points as the number of cards still in their hand while the one who went out gains points equal to the sum of points lost that round. If a player goes out with a 1 (the dog), then each player loses 10 points and that player wins 10 points per opponent. With the final variant, if you have a number in hand that matches the number most recently played, you can play that card out of turn. This clears the pile, then you can play whichever card you want to start a new discard pile.
