"You may not reload the game from a previous save file or an autosave file to replay and change any events that occur in the game. Reloading gives you an artificial knowledge of future events and might allow you to manipulate the outcomes of some random events, but these behaviors will often leave a distinctive signature on your game that can be detected by further review of your submitted save game files."
"To submit a full Game of the Month you need to play the game through to a completed victory of defeat condition. Your submitted game file should be from the last turn before your defeat or the first continuation turn after your victory. You only need to submit the final save file, but every player should retain backups of savegames on or around 2000 BC, 1000 BC, 10 AD, and 1000 AD. The extra savegames may be requested by members of the GOTM staff to help in validating the results of all the submitted games

"Here is a list of all known exploits and bugs in Civilization III. Green is allowed when playing the GOTM; red is disallowed.
ALLOWED
Right of Passage abuse
Make an agreement of Right of Passage, move your units to their main cities and attack them all at once.
Free palace jump
When disbanding your capitol your palace will appear in the biggest other city. Your former capitol can be rebuilt by the settler it created. This way you've moved you capitol free.
Island block
If you fill the coast of a certain island with units, even non-military, the AI won't be able to land, thus isn't able to conquer that island, until it has marines.
Ship hopping
While at sea, you can unload a ship on the same square where there is another ship and that ship can take over the load. This way you can move your units to any location in one turn. But it takes a lot of effort.
ICS (Infinite City Sprawl)
Build a lot of cities very close next to each other. This way you simply have more cities which are in the beginning just as big as normal.
DISALLOWED
Scout resource denial
Place a scout on a square where there is a resource and in (future) enemy territory. As long as you have peace with them you can leave him there undisturbed and the other will never be able to build a road to it.
Pop-rushing
In despotism and communism it is possible to use cities purely for unit rush building. Workers can be added to such a city and then the city can then use them to rush build units. This is disallowed, so do not create these kind of cities. Pop rushing one or two regular citizens to finish a building or to build a unit is within the rules and the spirit of the game. What is against the rules is joining workers to cities for the purpose of pop rushing.
Worker dogpile
Let all your workers join a city with a hospital and continue to build workers and let them join that city. There's no size limit so your city will become huge and you loose only one population per turn. All the workers become specialists and add to your score.
Gold mine
You can make cities give wealth and production at the same time. First set the cities to produce wealth. At the beginning of the next turn when another city is done building something else you can go to other cities with the arrows above and change the production of the cities that produce wealth to e.g. some unit. That will get production as well."
