Goblins Island Mining Tycoon vs Drilloot

"One day, you come to visit Goblin Island, a free, fun and exciting place. However, you discover that even though admission is free, you need a million coins to leave the island! What." Head to the mines, diligently mine for ore, and sell what you collect to earn coins. Acquiring a new pickaxe allows you to venture into deeper areas. As your capabilities expand, your coin earnings will skyrocket—transforming that steady, methodical digging into a satisfying rush of massive profits. This major update also introduces the new "Sandstone Area" and the "Drill Merge" system! Dig through sandstone to uncover drills, then merge three identical ones to level them up. Wield your upgraded drills to dig even deeper. Start by digging steadily, then watch the pace pick up. Turn a few spare moments into a little bit of fun. Why not aim for a million coins on Goblin's Island?
