Commonagrams includes:
51 consonant cards
21 vowel cards
17 extra credit cards
10 notebook cards
10 dry erase markers
1 sand timer
Each player gets a marker and a notebook card to write their words on. The decks are shuffled, and 3 extra credit cards are revealed, showing goals for players to achieve, e.g. "Most 4-letter words", "Most words with 2 vowels", "Longest word with 1 vowel".
There are 8 rounds. In each round a (gradually decreasing) number of consonant and vowel cards are set out, after which players have 30 seconds to write a word using at least 3 of the exposed letters. Each player whose word for that round matches the word of 1 other player gets 1 point; if it matches the words of 2+ other players they get 2 points.
After all 8 rounds, the player(s) whose words best fulfill each extra credit card gets 1 point for that card. The player with the most points overall wins the game.
