Bingo lists
A bingo is when you use all seven letters at the same time, and it scores fifty bonus points in addition to the score for the word. It is the "grand slam" of the Scrabble world. The key to scoring bingos is holding on to letters which are statistically found in many words. For example, since E is the most common letter in the English language, it is found in many bingos. Other important letters are A, R, N, I, S, T, L, and O.
A bingo stem is a combination of six or seven letters which can form many different words. For example, RETINAS can be rearranged to form the words STEARIN, ANESTRI, RETAINS, RETSINA, ANTSIER, NASTIER, RATINES, and STAINER.
The top bingo stems, and the words they form, are in the lists below.
