Speedy Words

From BoardGameGeek:

An addictive card game that takes the famous Categories game to the next level. No need for a pen or paper. In each turn, a player flips a card, thus having one category, and three letters. Only one letters has a color that matches the color of the category. The first player that calls out loud a relevant word that starts with the correct letter wins the card. When only one card is left the game is over. The player who collected the highest number of cards wins the game.
