The Noun Town series of games is designed to teach over 600 nouns. There are 4 levels of difficulty and 28 games in each level, resulting in over 100 games. Each game in Level 6 covers 24 nouns in a single topic area. Each Level 6 game has 6 possible choices. Each game in Level 5 covers 20 nouns with 5 possible choices. This pattern is repeated down to Level 3 where there are 12 nouns in each game and only 3 possible choices.
