Andrea Gilbert invented BoxUp on which TriBox is based.

In this warehouse you push the boxes from the inside!

Can you maneuver the small red box into the large blue box using only the small black Pusher hex and your own puzzle-solving skills? Can you use the dark boxes to help you to move the light boxes together, or will they just get in the way? Here are 24 challenging puzzles to help you find out!
