The year is 2100. Robots have invaded the Earth. Their bases are placed on secret list, and their weapons are ultra-modern and very powerful. Their arsenal is so large that one robots' attack can destroy the Earth at a moment's notice. It seemed impossible to conquer them, but fortunately human spies have found the army's weak spot: the robots are absolutely illiterate! You may gain advantages by beating the robots in the word contest and take possession of all their guns, bombs and other secret gadgets. Build as many words as you can and help human beings hold out against enemy's attacks and live peacefully.
