In this logical game you should unmine a sphere built of triangular faces. There is a figure on the face which tells how many mines are located under the bordering faces.

The goal of this game is to open all empty faces and mark all mined faces.

The game will be finished when the numbers of unmarked mined faces and unopened empty faces are equal to zero. Every time you win the game, the power of your armored jacket increases. When you open the face with the mine the jacket protects you from explosion and you can continue the game unharmed.
