About This Game

Planet Explorer Addition turns mental arithmetic into an interplanetary treasure hunt. Before your spaceship may visit each gem-filled planet, you must scan four addition expressions and single out the one whose answer differs from the other three. Choose correctly and the engines fire, unlocking another world to collect; stumble and you simply try again until the math clicks. The difficulty scales naturally with your confidence, sneaking harder sums into later rounds. It is a wonderful way for children to sharpen addition speed and for adults to keep their mental math limber, all wrapped in a charming space theme.

How to Play

Study the four addition expressions on screen and calculate each one, then use the mouse or touch pad to click the single option whose total differs from the other three. A correct selection launches your journey to a new planet, while a wrong pick simply lets you recalculate and try again. Keep exploring to visit as many planets as your math allows. Work the sums mentally first to build real calculation speed.
