How to Use: First, take out the 80 cards and the sand timer from the box. Read the rules in the instruction booklet to understand each of the 10 game variations. To start a game, flip a card to get a colorful letter and match it with the corresponding colorful quadrant on another card as per the game's rules. Start the sand timer and see how quickly you can come up with the right answers. For solo play, try to beat your own high score. Note: Keep the cards away from moisture to prevent them from getting damaged. Don't let young children play with the sand timer to avoid choking hazards. Maintenance: After each use, put the cards back in the box neatly. Wipe the sand timer gently with a dry cloth if it gets dirty.
