Challenging Brain Game - Minesweeper 3D

Rating: 5.9/10 - 10 votes

Minesweeper 3D is a new twist on the classic game, where instead of one flat grid, you have a whole cube to control! Your job is to successfully flag up mines and click on all the safe squares, after calculating which squares are safe. You can do this by considering squares with numbers, which tell you how many bombs they're next to (horizontally, vertically and diagonally all count). Once you've clicked all the safe squares, you'll win the level!

How to Play: Click or tap on any of the white boxes on the side of the cube. Numbers will appear on some of the surrounding boxes. These numbers indicate how many mines a box is next to. Your goal is to avoid clicking on the mines. If you think a box contains a mine, right-click so that you can put a flag there. You can rotate the cube to get a better look by clicking, holding and dragging, or pressing the arrows around the cube. Choose from various difficulty levels (Easy, Medium, Hard) and styles (Campaign or Arcade).

This HTML5 game works on PC/Mac and is unfortunately not compatible with mobile devices.
