Given away on Amazon App Store for a day, Lingrove is a word puzzle that is a bit like Mastermind, but with 5 letters (that must form words), not simple colors. You enter 5-letter words and you are told which letters are used and in the right place, and which letters are used but NOT in the right place. You have exactly 5 chances.
I never was very good at word games, such as Scrabble, so I was struggling with this one. There's a story to unlock, but there are a LOT of puzzles to solve.
Interesting, but not THAT interesting.
