Qranio is a mobile app where kids and adults can play, learn, challenge friends, and have the opportunity to redeem real prizes. There are lots of topics you can choose from, including history, TV, movies, music, technology, and more.

The game consists of 3 different modes: Classic, Knowledge Trails, and Duel. In Classic mode, you can pick from a variety of topics. The game will be a little different for each person, but in general, it's a game where you have to answer questions correctly to get a reward. The game is very easy to play and has a friendly interface.

The Knowledge Trails mode is similar to the Classic mode, but this time you have to complete a specific task. For example, you have to find a movie and answer the right questions. The task is different for each topic, so it's a little difficult to know what topic you have to pick.

The last mode is Duel mode. In this mode, you can challenge your friends to a game. The game is similar to the other 2 modes, but this time you have to fight your opponent to get the reward.
