From the package: The board game where fast fun adds up! Spell the numbers ONE through TEN using letter tiles. Spell N-I-N-E, score 9 points. Each word you spell gives you points equal to that number. Got it? Spell T-E-N and you're really on a roll! But, look out! If somebody else has the WO-O tiles, you could lose your T-E-N points and they'll be up O-N-E plus T-W-O! Reach 21 or more points and win! This easy-to-learn tile game is great for introducing simple addition and spelling concepts.
