Diggy is now available to play for free at Cool Math Games! Your mission is to help a guy called Diggy to and find the wandering truffle and reach the center of the Earth using a drill. Use your arrow keys to walk and jump. Move your mouse cursor anywhere around the screen to aim Diggy’s drill, then click to start drilling in that direction. Press E to activate Diggy’s radar and locate hidden objects, then drill to them and pick them up. There are 4 types of ground, easy, medium, strong and hard. The hardest type of soil is more difficult to destroy and it will take longer to dig into it. Every use of your drill consumes energy. When Diggy runs out of energy, use the money you’ve earned to buy equipment upgrades. You can upgrade your stuff after each accomplished day. There are 3 tools that can be upgraded, driller, battery and radar. Look at the costs and benefits for each upgrade and buy them strategically. This game is all about tactic and strategy and you will have to plan carefully! How long will it take you to reach the center of the Earth?
