Rainbow 7

In Rainbow 7, you discard one or more cards from your hand each turn, but they keep coming back...

The deck in this game consists of 49 cards in seven colors from 1-7, as well as four rainbow cards valued at X. Each player starts with a hand of six random cards from 1-6 and one random 7. On a turn, you discard a single card or a group of three or more cards that are either the same number or color; if you discard a 7 as part of a group, you carry out the special effect of the card, such as discarding a rain token or forcing everyone else to draw a card. Place played cards on the three discard piles as you wish, then draw one card from the top of a discard pile or the deck and add it to your hand.

Alternatively, if the sum of cards in your hand is at most 7, you can call "Rainbow [sum]", e.g. "Rainbow 3". If no one else has a lower score than you, you win the round, and everyone else gains two rain tokens; if someone is lower, you gains three rain tokens, and no one else gains tokens.

Finally, if on a turn you play out the remaining cards in your hand, the round ends, and everyone else gains one rain token.

If a player has at least seven rain tokens, the game ends, and whoever has the fewest rain tokens wins. If not, start another round...
