Parents need to know Mr. Mustachio: Word Search is a puzzle game for iOS and Android devices. To successfully complete the puzzles, kids have to carefully read the instructions, which can encourage them to be conscientious and thorough. The puzzles generally aren't too hard to solve otherwise -- many involve short words. Ads are shown fairly frequently between rounds, and kids can also buy things within the app. Boosters that will help them solve the puzzles -- such as an infinite time option that will pause the timer or hints that indicate two possibly correct options -- can be purchased using diamonds kids earn as they play. They can also pay $2.99 to remove ads from the experience. Otherwise, there's no inappropriate content in the game.
