Metal Digger is an Android game centered around coin and metal detection. Players can search for various types of metals, including ferrous metals, aluminum, and copper. The game also features a wide array of coins ranging from the era of Peter the Great to the Soviet Union. Additionally, players can come across antique crosses and rings as part of their findings.

As the game progresses, more types of metals and possibly various antique items will be added. Players have access to different detectors such as Response, Veles, Svarog, each differing in search radius and probability of finding heavier metals. For those focused on coin hunting, a special metal detector model called Beryl is available in the game, activating a coin search mode when equipped in the inventory.

At the start, players have the Response detector in their inventory, with other detectors becoming available as they level up and progress in the game. Embark on metal mining expeditions, search for metals, and trade in your findings to earn currency for upgrading to more powerful detectors, attaching trailers to your Niva (available at the beginning), buying a UAZ, and eventually acquiring the Lesnik all-terrain vehicle. The Lesnik not only boasts the highest load capacity but also unlocks access to a new location with the rarest coins.

Equip yourself with the necessary tools for excavation, including a shovel for digging and a petrol saw for cutting large metals. Achievements can also be earned in the game, adding an element of surprise and challenge to the gameplay.
