2x2 blocks - In order to move these blocks, the player has to make a white box completely around them.
Conveyor blocks - These blocks move the skull left or right, depending on the movement of the wheels.
Pipes - These work only if the player arranges pipe pieces together so that they all connect. When all connected, the skull being dropped into one will be transported through the network, out of the other end of the pipe
Chained blocks - Like large blocks, the player cannot move these if they have not got these entirely in a white box, but the player can fit blocks between these.
Left turning blocks - If this block has a white box placed around it, then the selected blocks will turn left instead of right.
Upside-down turning blocks - Including this block in the player's white blocks will cause all selected blocks to turn 180° (upside down)
Castle turning blocks - When the player includes this in a white box, the whole screen will turn upside down.
