Block
The Blockheads world is made of blocks. A Blockhead can rearrange the blocks to change the world.
To place a block select the desired block in the inventory then tap the place on the screen where the player wants the block.
To remove a block tap on the block to be removed. The Blockhead will travel to the spot and commence deconstruction. The removal process takes more time if your Blockhead isn't using the appropriate tool (the item selected when tapping on the block to remove).
Most blocks are "solid" and prevent a Blockhead from moving through them. They can, however, be climbed or walked on.
List of Blocks
Most of the blocks in the game can be collected or created by the Blockhead:
Crafting Blocks
These can be used in crafting.
Smelting Blocks
These are harvested to produce ore but not in the form of a block.
Construction Blocks
These have no known use in crafting, but can be used in construction.
Other Blocks
These blocks cannot be mined. Air and water are also all fluid, and will flow to fill available spaces.
Time Crystals cannot be placed, so they cannot be used for construction or decoration.
