Only twelve reviews so far, eight of them four star and above.
It's apparently a Tetris variation, cubes with numbers drop from the sky and you must pair them with other cubes to equal a predetermined number and thus prevent the wall from building up to the top of the screen.
KB Member Annalog says "I did not have time for a long test but the cubes drop in pairs, at least as long as I played. The sum goal changes periodically during the game. I think it would be a fun way to practice adding two digits quickly while also thinking about matching and manipulating the blocks. It worked well on my Fire."
