This game proves s-p-e-l-l-i-n-g can be a blast.
Players take turns saying letters and building words together. Someone starts with any letter, maybe an R. The next person thinks of a word, such as rake, and says A. The next person thinks of a word, such as rabbit, and says B. Each player must have a real word in her head before speaking. Players can pass a turn three times.
If you challenge someone and they don't have a word in mind, they're out. Last one left spelling wins.
