Orbox B

Another simple but engaging puzzle solving game. A shiny square, dormant when it stands but initiate a movement it stops not till it collides with a brick blockade. So being so it is to make the shiny block slip into a warp hole leading to another level. But the warp hole is not straight ahead to just go and fall in but is placed in a maze of blockades. So the gamer maneuvers the shiny block through the maze into the warp hole and this is not for a single level but 30 ... Wow. why wait and lets play the ORBOX B ...... :)

Starshine and Bloxorz

Two more games which are good.
Starshine - Resembles nuclear fission, where we bombard one star with another and it splits into two (or more). The aim is to bombard all stars using the split stars.
Bloxorz - Push a Brick Block into a hole. Seems easy is it not. But no. You need to move the block (rectangular cuboid) into a square hole (equal to the smallest area on the surface of the block). Play it to find it.
