So most people know this already, but the 4th rank in Lemmings Cranium, named "Challenge", are 30 levels that are purely subsets of levels from Amiga Lemmings, Oh No! More Lemmings and Genesis/MegaDrive Lemmings. Some of these challenges are rather specific with their limited toolsets, but it could be a good test to see how much you can minimise the skill usage and, in some cases, maximise the lemmings saved.
So if you're looking for 30 unique challenges based on the original game, that rank is for you!
