Dirt is a block in the game CastleMiner. It is unlocked by getting the trial or full game and appears in your hotbar. Dirt is very common in CastleMiner Z because grass is automatically replaced with Dirt in CastleMiner Z. If a player digs downward just 1 block, there is already dirt, unless the player is digging in the Mountains, Desert, Miner's Paradise, the Underworld, or the Tundra. Dirt is a surface block, because eventually after digging down instead of finding dirt, the player will find rock. Also commonly used for "block spamming" in CastleMiner.
