All the numbers are modulo 3! 3 becomes 0, 4 becomes 1, etc. Be wary of 3 mines cancelling out! 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). In this version there are regular mines, double mines which count for 2, triple mines which count for 3, and anti mines which count for -1.
