In the big challenges thread, someone posted this challenge for Fun 1: 100% with one digger and no lemmings bouncing off a left wall. To generalise this as much as possible (levels with exit further left than entrance, multiple exits or entrances, Cheapo / Lix levels with left-facing entrances...) I decided to rewrite the condition as follows:
Find all levels that can be solved with no individual lemming turning round more than once.Here's the current list for Original Lemmings and ONML:
FUN 1, 2, 5–28, 30 (100%: 1, 2, 5, 7–11, 13, 14, 16, 17, 19–21, 24–27, 30)
TRICKY 1–7, 9–13, 15, 17–22, 25, 26, 28, 29 (100%: 1–6, 9, 12, 13, 19, 21, 26, 28, 29)
TAXING 2, 5, 9, 10, 12, 16–20, 22, 24, 25, 27, 28, 30 (100%: 2, 9, 10, 20, 22, 24, 30)
MAYHEM 4, 10–13, 15, 25, 26, 28, 30 (100%: 4, 11–13, 25, 28)
TAME all 100%
CRAZY 1, 3, 5, 9, 11–13, 15, 16, 18–20 (100%: 1, 5, 9, 15, 16, 20)
WILD 1–3, 6, 8, 10, 15, 17, 18, 20 (100%: 6, 8, 17, 20)
WICKED 1, 3–8, 14, 16, 17 (100%: 3, 5, 14)
HAVOC 3, 4, 9, 10, 12 (100%: all except 10)
Fun 11 is particularly fun
and Taxing 28 is rather a neat puzzle, as it doesn't look possible for the challenge at first sight.
It has to be said, this is one of the more sadistic Lemmings challenges -- for instance, on Fun 14, you'll never make it if you try multi-bashing, so the way to fulfil the condition is to have the lemmings who turn round kill themselves by bashing through a left wall of the structure into the water!
