I was checking out the rule for Crazy Eight. In the Play it is stated "If unable to play, cards are drawn from the top of the stock until a play is possible, or until the stock is exhausted. If unable to play when the stock is exhausted, the player must pass. A player may draw from the stock, even though there may be a playable card in the player’s hand."

This last statement is a contradiction. How can a player be unable to play and have a playable card in his hand?

The player should only be allowed to draw from the stock if and when he or she has no playable cards in hand. Likewise, what is to prevent a player from continuing to draw after he/she has drawn a playable card.

Something is wrong here. Drawing from the stock should be telling the other player something about a player's hand. If they can't play on a seven of hearts, that should mean the player has no hearts, sevens, or eights (playable cards). That information should be useful to the other players. But if a player can hold a playable card and still draw? What is that saying?

I know I must be missing something here, but the statement "drawn from the top of the stock until a play is possible" is contradictory as it allows the player to hide the fact that the player has one or more payable cards.
