Everybody can read C source code.
Everybody knows the rules of popular classical board/card games.
Everybody is fit with high-school mathematics, in particular, high-school level calculus.
Everybody knows some mathematics beyond the high-school level, whether from formal education or by self-teaching. Hard to define how far I assume this; let's say, complex numbers, some graph theory, linear algebra, elementary set theory, elementary topology.

These ones aren't true for me, and not for most people I see in at least some of the communities I frequent. It does feel like it's true for most people I hang out with in the puzzler community, though.

I've been getting into Nikoli-style logic puzzles recently, solving a few when I have the time, but I also went ahead and created some of my own puzzles. They're nothing too fancy, but I'm pretty happy with them for a first attempt. They use a ruleset which combines Simple Loops with Nonograms. I dub it, the Nonoloop.


- Draw a single non-intersecting loop through the centers of all cells. The loop may only move horizontally or vertically and may only make 90-degree turns.
- Clues outside the grid represent the lengths of the blocks of consecutive turns that the loop makes in the corresponding row or column, in order.

E.g. "2" means the loop turns in two consecutive cells in that column, while "1 1" means the loop turns in one cell and then another non-consecutively.

Nonoloop 1 (click to show/hide)

Nonoloop 2 (click to show/hide)

Nonoloop 3 (click to show/hide)

Nonoloop 4 (click to show/hide)

And attached is a single pdf with the rules and all puzzles, if that's preferred

Regarding kaywhyn's solutions to my levels...

R1 and R2 are acceptable alternatives that have been seen before and are close to the originally intended solution. R3 is the intended solution.

Icho's solutions to my R1 and R2 are acceptable alternatives. R3 is essentially the intended solution.


Yet another new solution for my R1. So far, everyone who has solved it (including me) has used a different solution. They're all acceptable to me because it checks the boxes I wanted to see, yours included. Nice job.

Apjjm's solution to my R1 was entirely acceptable.

The solution to my R2 is very different to Armani and I's... but it does still use every skill, so I'll tentatively keep it as an alternate solution. I'm satisfied with my R1 and R2 being relatively open-ended.

Updating DireKrow's R3 Level, "Ancient Lemmarine", from V1 to V2. Changes:
- Widened some gaps in the terrain to prevent a backroute discovered by Armani.
- Removed 2 superfluous climbers from the skillset.
- Minor scenery adjustments.

Your first replay of my R3 level was exactly the intended solution. The second replay is a backroute. Will fix that tomorrow.

I talked about it on the discord, but I'll put here too for the record. Armani's solution to my R2 level is acceptable. It saves a skill, but honestly... I'm weighing up the idea of making Armani's solution the canonical one and officially removing that saved skill from the level.

played through all rule1 levels. 8-)
They all probably are not quite intended :sick: other than Icho's level which is I'm pretty sure open-ended.

For my level... it's much closer to the intended solution than you think! You solved all of the 'problems' you were intended to solve, and used most of the skills in the places you were intended to use them... you just did it in a way that takes a lot longer and was slightly more complicated, but saves a skill as a result.

I think I'm okay with leaving this as an alternate solution. I'd rather err on the side of keeping it a little more open-ended, to make it more accessible to people. Plus it provides a way to solve it without having to multitask, which I think people will appreciate.

If I really wanted to block this solution, then adding a 2:30 timer is something I could do. It would fit the level too, since some base infiltration have to be done under time pressure, after all ;P But I don't feel the need to do that yet. Another option I'll consider is to make beating it in <2:30 into a talisman.

For Rule 2, you can have 10 terrain AND 10 objects. 20 'things' in a level total. Any entrances and exits DO count as objects.

- The OWW in Redirect Loop can't be bashed from the expected direction, instead acting like steel. This renders the level unsolvable by its intended solution.

- The 2nd spring in Steps to Success causes the lemmings to splat against the cross-beam in the middle of the level. This renders the level unsolvable.

- Changes to the trampoline physics render Breaking the Routine unsolvable. See discord message here for details. Tl;dr Lemmings bounce slightly too high.

- The 3rd bomber in Entanglement is pixel-perfect in Loap, where as there's slightly more of a window in L3D, due to physics differences.

- In L3D you can place blockers directly in front of the exit. In Loap, they exit the level if you try this.

- Several levels have cameras that are stuck in ceilings at the start of the level. Most common on indoor levels like Alilemms and Infinite Lemming Drive, but it can also be seen in That's Right for instance. The camera is also practically unusable in Catacombs.

- On rare occasions, attempting to assign a skill to a lemming will instead assign it to one behind the camera or way off in a different part of the level. It's unclear what causes it (possibly rewinds? Might be a coincidence). When this happens, strange behavior can be observed from the indicator in the bottom left that says what skills the lemming you're hovering over has (such as saying WALKER despite the mouse not being on any lemmings), which suggests that the bug exists in detecting what lemming the mouse is pointing at, rather than the skill assignment itself.

- Loading a replay on the preview screen with L causes the camera to rotate when you start playing the level, as if L was held down, until L is pressed again.

- Rope slides look visually bugged down their length, but otherwise function correctly.

- The pharaoh lemming heads are visible on the flame traps in Firewall, where as they're invisible in L3D.

- Missing sound effect: In L3D, when you reach the save requirement in a level during gameplay, it plays FANFARE from the sound rips. The rip is noticeably faster and high pitched than it is in-game, so I suspect it's played back at half speed.

- Extraneous sound effect: frame stepping forward should be silent instead of playing a sound.

- Not a bug, but playtesting indicates that making it so you can't assign blockers/turners inside of splitter blocks (as in L3D) is probably a good idea, as the currently behavior lets you trivialize certain levels like Spaghetti Junction and 3D A Lemming Odyssey

- Also not a bug, but many in-game cosmetic animations seem to play too fast, such as the wall monitors in Lemlab themed levels and the mud. L3D on DOSBox already seems to play these too fast so it can be misleading, but I'm pretty sure they're meant to be slower.

- Unlike L3D, the engine doesn't seem to tint top and bottom faces, which gives some levels confusing visuals, where walls, deflectors and platforms blend into each other. Firewall is an example. See discord messages starting here for details.

I think it might be a good idea to have an option to disable playback of replays entirely unless explicitly loaded. I wouldn't use it myself, but we've just had someone ask for it and it's something I can see other people wanting.

Levels submitted. Good luck to the competitors. Looking forward to playing what other people come up with.

...what do you call them?
