In Speedeebee!, players race to complete challenges presented to them while using – or not using! – the letters rolled on four dice. Each round players are presented with a challenge on one of the fifty challenge cards; each card has three challenges, and the challenge to be used is determined by the color on the back of the challenge card previously won. Someone reads off the challenge – for example, name something taller than five feet starting with one of the rolled letters – then the player rolls the letter dice. Whoever calls dibs first and names something correctly wins the card; if a player makes a wrong guess, he's penalized one card that he claimed previously. Whoever has the most cards after going through twenty challenge cards wins!
