Box Challenge

Box Challenge is a fun game in which you have to grow the box to exactly the right size. Tap the box to grow it and let go to release. The block will fall down. Make sure the box fits exactly into the slot below. If the box is too small, it will fall through the hole at the bottom, but if it is too large in won't fit into the slot. For each level, you will have to fit an additional block to move on. For instance, in level 4 you must count down 4 boxes to reach level 5, in level 5 you must count down 5 boxes to reach level 6, etc. How far can you get?
