Gold Digger Master

Come and play this brain training game!
You will become an experienced miner and use your shovel to dig for precious treasures buried deep underground.
Meanwhile, the naughty groundhog will hide these treasures and wait for you to compete with them!

This is a derivative game based on tic-tac-toe. It adds a setting of only keeping 3 pieces, which tests the player's memory and gaming ability.
As the level increases, there will be more difficult AI waiting for you to challenge!
