Some pieces have special attributes, the Spy can only kill the Marshall if it attacks, it looses to any other unit. The Scout can move as far in one direction as you want, but it is the weakest piece on the board. The Miner is the second weakest piece on the board, but it can defeat bombs. Bombs are immovable pieces that if attacked kill every unit except the Miner. In the case of a tie, both units are removed from the board.
Players take turns moving one piece to a new location or attacking an opponents piece.
You can also look at which pieces have been defeated already to better plan your attack. Computer Stratego includes the classic game plus five new games for you to test your skills.
