DuO 3 - Mines is the third game in the DuO series. Just as in the other DuO games, you work with two different colors, where one of them must form a single group. In this version, we have mixed DuO with a classic mine sweeping game. There are clues on the board that tell you the number of neighboring squares that contain game pieces with the same color as the clue. Each puzzle can be solved in a step-by-step manner, and you should never have to guess. There are two versions of DuO 3, each with an unique set of puzzles:

This free version contains 64 puzzles in 4 different sizes, from 5x5 to 8x8.

The full version contains 1248 puzzles in 4 different sizes, from 5x5 to 8x8. For each size there is a set of bonus puzzles where the rules are a little more difficult. Instead of showing the exact number of neighbours they show some, but maybe not all of them! Also, you do not know from the beginning which of the colors that must form one single group.

The game includes both a Swedish and an English version.
