The year is 2025 and a race of X Aliens is threatening the intelligence of the human race! You are one of two human droid bots that are the human race's only hope. The bots, named Zirus and Gaya, can beat the aliens by answering the questions they shoot out. The faster they answer the higher the score and the better chance they have of winning. There are a hundred questions in X Challenge-Mental Math, so get ready to think fast.
Only three mistakes are allowed before damage occurs, so be fast but be careful. The game can be played in easy, medium, or hard mode, so working your way up and staying challenged is always possible. Compete with other players worldwide on the Swarm leaderboards and see how you rank. With over 1000 questions total and new updates coming all the time, there is no question this game is fun and educational.
Have a blast and keep your mind sharp at the same time. All ages can benefit from this. The young can do better in school, and the aging can ward off dementia simply all by fighting aliens and saving the world.
