Lettery! is a word guessing game that can be played with words that contain 4, 5, 6 or 7 letters. Similar to Wordle [note: Lettery! is NOT sponsored nor endorsed by the owner of Wordle], Lettery! selects a hidden word, the player guesses a word and Lettery! indicates which letters in the guessed word are in the hidden word in the correct location, which letters in the guessed word are in the hidden word in an incorrect location, and which letters in the guessed word are not in the hidden word. A player uses that information to make 7 consecutive guesses of the hidden word. Each day Lettery! selects four new hidden "Today's" words; one word with 4 letters, 5 letters, 6 letters and 7 letters. Each Today's word can be played once. All players are given the same set of "Today's" words each day. A player can also play any number of additional words that will be randomly selected from Lettery!'s 2000 word dictionary of 4, 5 and 6 letter words and 800 word dictionary for 7 letter words. Every guess for a word is spell checked. The player is given the option of allowing a misspelled word as a guess for the additional words but not the "Today's" words. A player's results for any of the Today's words can be posted to social media, messaged or emailed to others. You cannot post results if you tapped the Reveal icon at the top to reveal the hidden word. A successful guess of any of the Today's words is tallied and posted anonymously so you can compare your daily results to others. Scores include: * Today's results (e.g. be the first to successfully guess a 6 letter word in less than 4 guesses), * Yesterday's results (e.g. did anyone guessed the word in 3 guesses), * All time guesses (e.g. on average how many guesses does it take to solve a 7 letter word), and * Streaks (e.g. over how many consecutive days can you solve the 4 letter word) Lettery! has an intelligent keyboard that indicates whether a given letter can be correctly placed in a given position based upon the information in previous guesses. The colors used to indicate correctly or incorrectly placed letters can be altered by the player. Letters from previous guesses can be copied and pasted to a new guess. Shown in the images are: 1) A 4 letter word game 2) A 7 letter word game 3) The choices for a new game 4) Revealing the answer for a 6 letter word game 5) The Twitter post for the 7 letter word game 6) The color adjust screen

Lettery!'s advantage is ads (none vs shown) and ratings volume (3 vs 1). On price, rating, review sentiment and device support there is nothing between them.
