My players would murder me. They're terrible with number puzzles..

You can do mass replace from the symbol manager. Just pick the symbol to replace, and then pick the one to replace it with. Note that the symbol you wish to replace with already have to be placed in the map once, otherwise it won't be in the symbol manager list.

Note that you can only replace one symbol type at a time, there isn't a way to simply replace varicolor to non-varicolor.

It's mainly CPU-bound, but the speed of your drive (for loading artwork) and speed of your RAM will influence things. And while things like effects do take advantage of multiple cores, I also find it helpful to have a CPU with a high single-core performance. It's better with a handfull of cores and high performance per core, than a huge heap of cores with lower performance per core.

Perfect for when my players encounter those scary monsters.

Happy New Year everyone.

Just a reminder that this little challenge is still open until January 16th if you want to give it a go. Keep in mind this is just for fun, so don't feel intimidated by all the fantastic entries so far.
