The short: Red and green make yellow, green and blue make cyan, red and blue make magenta, and all three combined cancel out. The long: Imagine a grid. Every red mine is one step to the right. Every green mine is one step to the up-left. Every blue mine is one step to the down-left. This is all aligned right to make a nice triangular grid. The number is the distance from the center, and the color is the angle. Your goal is to dig up every space except for the mines. Use flags to mark where you think mines are. Numbers tell you how many mines are around it, including diagonals. Click to dig, space to flag. Space cycles between all the different flag types and then back to no flag. Arrow keys to move the board around (this can also be done with the buttons in the top right).
Keep your eyes peeled for any performance issues because this one's a real doozy!
