For the first time a classroom puzzle might be fun. Solve the problems by dragging objects, squares and other geometric shapes and stacking them. It's important that no tool, no matter how boring their use can be during classes, fall from the simple and tiny platform placed in the screen. Make sure that a good strategic plan will keep everything safe and steady, then let the game check and advance to the next and obviously harder level. No Math involved, only good perception and accuracy. Stack school items, one after the other with the Mouse, and good luck becoming a master in this challenge.
