About Addition Factory
Run the conveyor belt in your very own addition factory! Numbers roll in on two conveyor belts and you must type the correct sum before they crash at the end. The factory speeds up as you progress — can you keep the production line running?
How to Play
Two numbered boxes roll toward each other on conveyor belts. Type their sum and press Enter before they collide. The closer they get, the less time you have.
