Walkthroughs for custom maps.

Some maps are designed so that players need to use different exploits to complete them.

No, but if we exclude thematic exceptions like bug-race or season's challenge, there are exploits like: firing and buying back a hero on the same day, or the Admiral's hat, or the earthquake/clone/berserker exploit, etc. Of course, everyone is free to decide for themselves what rules they want to play by and set their own limitations. I'm just curious how it's generally accepted to play maps in different communities, even in Chinese or European ones.
