A nice 3D version of the classic Windows 'tool', Bombsweeper 3D features a variety of polygons with an increasing number of sides to test your puzzle solving and deduction skills. Although much of the game's text is in Japanese, anyone even remotely familiar with Minesweeper will be able to pick up and play this game without instruction. For everyone else, bear with me...
The object, of course, is to identify all of the sides of the polygon with 'bombs' and to clear all of the sides without. Click on a side to clear it. If there is a bomb beneath the side you choose, the game ends. If not, the side will show the number of bombs that border with that side. If no number appears, no bombs border the side.
Press the space bar to toggle on and off the cursor bomb selector (*). With the selector turned on, click a side to guess that a bomb is hidden there. If you guess wrong, the game ends.
Click and drag the mouse anywhere off the shape to rotate the polygon and to view all of the sides easily.
A simple yet effective implementation of a classic game turned 3D. Click.
