This is Container. A simple word game where you need to type a word containing one letter, but can't contain another letter. For example, you could be asked to type a word containing K, but not containing D.
Music from Storyblocks Dictionary from InnovativeInventor on GitHub (WORD ADDING) There is only a very small amount of 187478 words possible (I'm so good at sarcasm), however, if you find a word that isn't in the list, tell me in the comments and I'll check it's a word, and then add it if it is. As this account @OSMANiCTeam is not yet a Scratcher, there is no high score counter, but I'll add it when I'm a Scratcher!
