I somehow missed this topic, but remember having seen documentation for this before.
A bit of digging and I found the documentation and code by Herman Perk from 1994, see attached.
I haven't checked but maybe worth comparing to see if there are any insights that you discovered that are missing, or vice versa.

Just briefly looked through the VOD and I heard you say (in response to Flopsy "you sound like geoo when the frog is getting fed in Lix") that I drew the frog. But I can't claim credit for that: NaOH drew the frog. I just added the two alternative animations. 

Quote from: Proxima on April 25, 2026, 07:19:55 PM1-23 Canopy Lemmings: Definitely a more interesting Rock 10-of-all than Biosphere. As mentioned above, since geoo was against 10-of-all repeats I will remove this level if he wants, though I would really like to keep it.

If this level is one of the more interesting 10-of-each levels, feel free to keep it. I'm more concerned about keeping the 10-of-each levels to a minimum rather than explicitly avoiding repeats (and if we have to use many of them, at least interleave them with other kinds of levels).

I'm not a big fan of padding packs with a bunch of 10-of-each levels at the beginning (regardless of whether they are repeats or not), especially if it's a long chain of them. I find them rarely interesting, and usually they are just work and become repetitive really fast. I guess talismans can sometimes spice them up, but I still think the fewer of these the better.

I think there's a difference between easy and beginner friendly. Sure, levels with lenient skill sets are beginner friendly as they allow players to explore mechanics. But similarly, levels can have a small set of skills (in particular few different skills) and only use straight-forward mechanics and thus be beginner friendly and yet not easy. For example, I wouldn't find it outrageous if "Eeny, meeny, miny... OH", "Little miner puzzle" or maybe even "The Placement is the Key" appeared in the second level slot. They are still accessible to beginners but arguably more interesting for the seasoned players. At least these could be interleaved between the 10-of-each levels.

Maybe this is moot anyway as I suspect pretty much anyone playing custom packs has enough familiarity with the game to be beyond "beginner" level anyway.

The corresponding post is in the Help subforum: https://www.lemmingsforums.net/index.php?topic=3273.0

(We were discussing a restructure of these but didn't get around, maybe the L1 topic should at least link to the ones for L2 and L3.)

I agree with Simon and Mindless here: Don't have a dedicated levels subforum, but keep the grouping by engine within  Other Lemmings Projects. The mods for each engine decide how to structure the board (e.g. Lemmini is flat, SuperLemmix has a bugs/suggestions subboard).

Create a single board for CustLemm/Lemmix/Golems in the Other Lemmings Projects section that will mostly feature historical threads that are currently in Levels for other engines but also any other discussion around these engines.

Levels for other engines will then be lean and only feature levels for more obscure engines. (On that note: I saw a Loap level topic in board which could be moved; and do we maybe want to make the L2Player board include L2 more generally and move level topics there?)

If I recall correctly, Cheapo runs reasonably well on Wine, there was just a few UI annoyances I think.

Can't check right now as I got all the Cheapo stuff on an external hard drive.

Quote from: JawaJuice on December 25, 2025, 09:26:07 PMAre you purely focused on Lix now, @geeo? I haven't seen your levels crop up for a while in NL LDCs (although to be fair, aside from #33, I've only played up to about 15 - got side-tracked playtesting various packs).

I've never actually designed a NeoLemmix level (as far as I remember). The early contests were for Lemmix (and the "no glitches" rule was already a novelty), and in later contests I submitted Lix levels. The whole NeoLemmix scene passed by me. I migrated to Linux around 2014, generally became less active and with NeoLemmix not really working on my computer the little time I spent on lemmings was for Lix. Nowadays NeoLemmix runs reasonably well in Wine (not sure about the editor), so every now and then I try to at least look at the contest submissions.

I appreciate mobius (and probably occasionally other people) remaking some of my levels for NeoLemmix though so that the NeoLemmix community also get to play them. I wasn't particularly aware of this until kaywhyn pointed me to Revenge of the Lemmings just now. Thanks for that!
I was just looking at the level list and there are some levels attributed to me that I don't even remember creating, probably from the Cheapo days. I think that'll give me the chance to solve some of my own levels from zero, which I guess is not something one often gets an opportunity to do. I should definitely play this at some point.

kaywhyn, I watched your LP for Stroke at Retirement Age, and you basically had all the skill placements down after 20 minutes. Really interesting to see that the hard part was realizing that this works if only you change the timing. And similarly interesting to know that you had a hard time with Merge Sort. For Lix I actually made a small level pack exploring these flow control ideas if you're curious. It ships with the latest Lix release.

Back in the early days I had similar trouble with tseug's Oh No, Not Again (is that in RotL as well?); it took me 4 years to solve that as my intuition for how the lemmings moved was completely off and I never thought feasible what ended up being the solution.

JawaJuice, I'm surprised timing the basher was an issue as you can release it pretty much whenever you want and just savestate back if it doesn't work. I guess if your setup in the rest of the level isn't ideal then the basher timing becomes more difficult than it should be.

When I linked this topic, I was looking at the sticky topics in Level Design, which has Lemmings games, editors and setting everything up as a crosspost to this topic. I didn't even realize that this topic has a different title.

This is a bit of a mess.

In Lemmings Main, we have How to play Lemmings (1991) on a modern PC and How to play and create custom levels. I think this is a sensible choice (except that maybe we want to include other lemmings games in the first topic as well). At the same time, it makes sense to cross-post these in Help & Guides and at least the latter one in Level Design.

In Level Design, we have Lemmings games, editors and setting everything up which serves the same purpose as How to play and create custom levels but instead points to this topic. I think we should update the latter to include some additional information from this topic (maybe with outdated engines hidden in a collapsible tag or linking to this topic), and archive or update this topic (it has seen some updates in 2022, but is still not up to date).

In Help & Guides we have a whole load of sticky topics: This topic, one each for how to run L2/L3/L3D/Revolution, and Playing Lemmings 2 without L2-FIX (which I think can be unstickied and linked in the How to play L2 topic) and .lvl and .dat: How to play and edit (which I think can be unstickied and referenced by How to play and create custom levels. I'd suggest to update How to play Lemmings (1991) on a modern PC to include links to the corresponding topics for L2/L3/L3D/Revolution, change the title and also crosspost it in Help & Guides.

While technically it is possible to play (older) custom levels in WinLemm, I'd recommend installing NeoLemmix and/or Lix. More details in this post: https://www.lemmingsforums.net/index.php?topic=1618.0

Most modern content is designed for NeoLemmix and Lix. WinLemm uses the .lvl format from the original game, which limits it to the feature set from the original game. You can find a lot of level packs compatible with the original game in the Lemmings level database: https://lldb.camanis.net/ But if you want to play those, you might as well just play them directly in the player that's part of the level database Otherwise, you have to download the packs, and either play them in Lemmix, or unpack the .dat files into .lvl and overwrite some original levels in WinLemm (which then has different physics so some level may not be solvable).

To give a bit of a backstory, in the early level design contents the goal was to make hard levels (rather than popular levels). The main aim was to solve as many levels as possible, so getting a hard level in gives you the edge over other players. I designed Stroke at Retirement Age with the aim that nobody could solve it, and while execution difficulty wasn't the goal it was a necessary evil I was willing to accept (especially after a few backroutes forced me to make the timing tighter). I didn't fully succeed as ccexplore managed to solve the level, but if I remember correctly it was still the level with the fewest solves in the content. Here's the old contest thread (as you can see it scored pretty low on the fun scale).

So congrats to you two for solving this one! I've always wondered how hard to figure out the level really is if you take away the execution difficulty. I feel like a lot of placements are forced, and the key novelty is the flow control which is complex but falls into place once you know when to place the key skill. Would be curious to hear your opinion.

The title was meant to be a clue to help with execution:

Spoiler

You assign the miner when there are 66 lemmings out of the hatch -- this is one of the statistics displayed in the original game and early Lemmix, I'm not sure if NeoLemmix still displays it.

In the Lix version, I could ease things up a bit by setting a fixed spawn interval to make the chain of lemmings longer, which should disadvantage the backroutes and thus allow me to give more wiggle room to the intended solution. Knowing the timing hint from the title I managed to execute the solution within 5 minutes, but I wonder how bad it is if you don't realize what it means.

The level design culture (and also my philosophy) certainly has evolved since then...

I'm curious to see what you've developed. Back in 2008 we tried to play Amiga Lemmings over network through emulators (and it was laggy and the gameplay wasn't great either, still good fun for the first time trying). Since then I've played a lot of networked multiplayer through Lix (and in the early days also Clones), and I think both engine and level design has come a long way since then!

Simon, the dev of Lix, might also be interested.

I'll probably be free the next two weekends. Only got Linux.

I'll be joining (in less than 3 hours from now).

I can definitely recommend it. It's a fun game, and even after many rounds, I still don't know what's the best strategy. You need to adapt to how the other players are playing.

I tried the simplified version (game ends when the pile is depleted, -1 for each remaining card) three weeks ago. They dynamics are definitely different near the end of the game, which is not necessarily a bad thing. What felt unsatisfying to me was that if you have something decent on your hand, you might not get another turn to play it (it's rather unpredictable when the game ends), so you either rip it apart to respond to some other player's sneak, or not play it at all. Counting 0 instead of -1 per card makes makes the latter option slightly less painful, but still not satisfying. But I'm curious how the scoring change affects the dynamics, maybe it simply becomes more predictable when the game ends.

Either way, this simplified version might be a good starting point for new players to get the hang of the game, and the final flaunting round can be introduced after one or two games. (Emphasizing "round": I'm not convinced by simply scoring the flaunts, as e.g. a flush and a straight flush get the same points then. The flaunting round is more strategic than it sounds and often brings interesting surprises as you have no clue what other players have left.)

While I'm not very visible here most of the time, I'm usually lurking and skimming the forum every day.

From now until mid-October, however, I'll be on the road and won't be checking the forum. The situation will probably be similar from mid-November to mid-December.
