there is the option of having a specific spot being a "vision area" if you move into this GREY area you will be exposed then vanish once you leave that spot. the game would be played on a open board with GREY areas that are in designated locations (volcano like spots). then it depends on your memory or your tracking ability. So you are not limited in your movement but there is that danger that you have to reveal your pieces. but here is the catch... you have to play with one less spy than normal. Play this on a 10Vx11H board with 4 GREY areas. If the Spy comes into a GREY area he can have SUPER VISION but he is destroyed at the end of your opponents move and any piece that it sees is permanently visible. All other pieces that go into this area will not be destroyed but are just temporarily visble to your opponent. Your pieces will be as follows Two 5s, Two 4s, Three 3s, Four 2s, Six 1s, Four Sapp, and Four Spys. Four bombs, 1 flag. The game is played on a 10x11 board and the grey areas are in the middle on the 2-5-7-10 squares horizontally.

Dark prince has a very excellent idea with the erupting volcano. i like that!
