Tools drop onto the seam and break blocks top-down — Chisel 1, Pickaxe 2, Drill 3, Blast 5 damage. Clear a whole column to open a Strongbox (2–100×, they add up). Three Lanterns start Deep Dig — four digs on a persistent seam, and the counter resets to four every time a tool lands. Extra Chance costs 3× the stake, pays on 3× and hits Deep Dig about five times as often. RTP 96%, max win 5,000×.

Autoplay spins for you and plays Deep Dig automatically, up to 25 digs per bonus — after that it hands the board back so a bonus is never spent while you are away. Extra Chance and the stake are locked while a run is going.
