This is a very old educational game aimed at teaching children arithmetic. Math problems drop out of a funnel, and collect in the buckets below. By typing in the correct answer before it hits the bucket, it will stop it from sitting in the bucket because when all the buckets are full the game is over - so to keep them empty, you must solve the equations.There are options to change the speed that the equations fall, and also the type of problems that fall from the funnels. Quite a fun game to play, and although it was created to help children learn the game is still very challenging for adults due to the fact that as more and more equations have been solved, they drop out from the funnels faster and faster.
