stardew valley how deep is the mine

The mine in Stardew Valley is 120 levels (floors) deep. Players progress through these floors by finding ladders at the end of each level after breaking rocks or defeating enemies. The floors are divided thematically into three sections of 40 floors each, with varying ores and enemies. After reaching the bottom at level 120, players receive the Skull Key, which grants access to the tougher Skull Cavern mine in the Desert.
