To Unlimited, and Beyond

From BoardGameGeek:

In To Unlimited, and Beyond, a.k.a. Chip It, players need to rid themselves of both cards and chips to win the game. The problem? Getting rid of your cards might require you to take chips! Each player starts the game with a random hand of cards and a few chips. On a turn, you either play cards to the center of the table (with you beating the cards previously played, if any) or return two chips to the stock. In more detail, the first player to play cards lays down one or more cards of the same value. You can take chips from the stock to alter the value of the cards you play. With a red card, each chip you take adds 1 to the value of that card; with a yellow card, each chip you take adds the value of the card to itself. If you play a red 7 and a yellow 4, for example, you can take two chips from the stock to make the 7 an 8 and the 4 an 8, and now you've played a pair of 8s. (Chip It has green and purple cards instead of red and yellow ones.) To play cards on top of this, you must play a pair of 9s or some stronger pair. If you cannot play or choose not to play, you must return two chips to the stock. You are still in the round, but if all players pass in turn, then the player who last played cards clears the pile and plays whatever they wish (or returns two chips to the stock, passing the lead to the right). Whoever first has no cards in hand and no chips in front of them wins!
