Enigma: Brain teasers, developed by Pol Apps, is a free trivia game available on Android. With over 100 puzzles of varying difficulties, it offers a wide range of challenges for users to enjoy and test their skills. The game includes puzzles on math problems, logic, turns of phrase, graphics, and lateral thinking, among others.

The game provides detailed solutions for each puzzle, allowing users to self-assess their solutions found. It also includes game stats, a search function, and a text-to-speech system. Users can share riddles with friends, but the feature is not fully supported on Facebook for Android. The game supports English and Italian languages and allows users to reset their saved scores.

Overall, Enigma: Brain teasers is an excellent game for those looking for a challenging and entertaining experience. The puzzles are not the type that will make you laugh, but they will engage you and put your skills to the test. It is a great way to spend time with friends and family, and I highly recommend it.
