Here is a quick trick that I used, but definitely will save you 30 mins + easily. so link for the question mark [?] link is going to look like the following neopets. com/games/snowwars.phtml?type=attack&cell=0 <---- this zero refers to the number of the position where the attack happens. change the number from 0 to -> any of those following [0 or 2 or .....4.6.8.] [11,13,15] [18,20,22,25]....etc these number sets the coordinate for the diagonal space....or like every other space. Once you saved them as a link, just open them all at once instead of clicking on the position and wait. (you need an account to see links) I finish each round of snow war in less than 5 mins cause I have the link saved already. Even if i don't win, I can still try it again and earn the trophy easily. Hope this helps
@(you need an account to see links) sorry about that, I must have closed out ht editor without actually saving the new links to the games, I'll do it again.
As for programs, there are a metric ton of them on this site and others, as well as many more greasemonkey scripts to choose from, so I'll just leave it up to you guys to find them.
