Grey rock appears grey coloured, hence its name, and appears to be made of many irregular sized rocks.
Rock appears usually as platforms for ice or other objects in levels. Rock cannot be cut across, and is usually placed in places which the player will have to work around. Usually rock appears suspended in the air, like most platforms in games, although some levels has rocks extending down into the water.
Spotty rock is a type of rock that first appears in Ice Breaker: The Gathering. It has a similar appearance to the normal rock, although it it is darker and has spots on it. It is unstable and will move ice near it is cut. It can be made immobile by clicking on it, which will insert a screw into it. The screw can be removed by clicking on it.
It has a different appearance compared to the ones in the flash series. It is a very dark brown with several darker cracks in it. Instead of wispy hands, there are are multiple runes with bright hands on them.
When the player clicks on the rock with their mouse, and drags off the rock, their cursor will turn into a hand. What seems like electricity can be seen attached to the hand coming to the rock. If the mouse is let go while he hand is on another rock, the hand will begin to hold on to that rock. The energy behind the hand can be passed through by any rock, which prevents the field from being a platform. The player can bring as many hands out of the the rock as they need.
Hands can even hold on to blocks that are in water. Hands are used in Ice Breaker: The Gathering for puzzle solving, most of the puzzles which involve having to catch falling materials. The more hands on a material, the more smoothly it moves. To deactivate a hand, the player has to slice across the electric field. Attaching hands onto objects does not count as a cut.
