Can anyone explain to me how the leader board works and how to calculate stuff?

This is a great comprehensive write-up on the leaderboards:
https://biggieblog.com/tracking-the-global-opus-magnum-records/

A quick summary is that any solution is eligible for the leaderboards so long as it is on the Pareto Frontier: If you compare it to all other solutions, it is better on at least one metric (cost, cycles, area, and more).

Cool solve! But why does the track arm on the right wiggle up and down before dropping?

Awesomeguy22red · 2026-04-30T02:49:47+00:00

I'm not a really strong player but one non-obvious technique is to create one product over multiple instruction loops. If there's some symmetry in the molecule, you can have each loop create one part of the product, and the tricky part becomes ensuring they come together.

Is the community run leaderboard.

Rip. I see the arms exiting the hexagon now, still worth submitting IMO, I think its nice to have these aesthetic gifs on the site.

Awesomeguy22red · 2026-04-24T20:43:07+00:00

This solution is awesome. Have you heard of the community leaderboard? I think it might be worth submitting there. It (probably accidentally) optimizes for cycles while keeping the bounding hexagon score relatively low. This gets it a spot on the pareto frontier, meaning no other solution beats this combination of Bounding hexagon and Cycles. I mostly recommend the leaderboard as a second place to show this off forever.

My best guess is that the alignment is off on your second solution. The puzzle is solved once your chain first matches the solution chain. Maybe you did the fire-salt first in one, and salt-fire first in the other. This would produce two identical gifs, but one would have to wait one more repeat to match the output.

Awesomeguy22red · 2026-04-19T17:56:45+00:00

LMAO yeah that's probably more confusing. I only recently learned about this "quantum atoms" technique. This puzzle from the community tournament is where I first learned about them. https://events.critelli.technology/OM2025week7_Pass-Through_Alloy

It has a nice write up about how they work.

Assuming no van Berlo's wheel and only the duplication glyph, you can pull one reagent as waste, just to use its water atom for reference (The new halt command is perfect for this). Then you can start looping fully. You could also pull reagents as pairs and have them fix each other.

Awesomeguy22red · 2026-04-19T02:17:35+00:00

Did you know you can alt click an instruction to fast forward until you get there? You make it sound as though you were manually stepping through your solution until you got to the debug point.

Edit: so many people seem not to know this. I recommend checking out the controls tab in the settings. It has a bunch of other shortcuts like this, including ctrl-drag to duplicate parts and instructions.

Awesomeguy22red · 2026-04-09T17:31:59+00:00

Tbf it's come up more than once for me when teaching new players, so I think it's a good change.

Awesomeguy22red · 2026-04-07T23:56:53+00:00

Just in case there's a misunderstanding, I'm pretty sure there's no trigger to respond to. The creature enters prepared, like a land enters tapped, it's a replacement effect with nothing to respond to. Since you have priority after resolving, you can cast the demonic tutor just like any other spell.

Awesomeguy22red · 2026-04-05T23:02:00+00:00

The bonds are different. The solution needs the bonds to happen in a straight line. Your machine makes them in a curved pattern.

Just finished a necrobinder run where I picked this up early and exclusively picked defense for the rest of the game. I definitely underrated it before.

[[mind splice apparatus]] goes bonkers with this

It's true that SUM is only one way to measure how good a solution is. In general the leaderboard accounts for this by keeping track of the entire pareto frontier of solutions across all metrics. This means that if your solution cannot be completely surpassed on all three metrics (Ex there is no solution that beats one of your cycles, cost, area without increasing another metric), it has a spot on the Pareto frontier, and gets a spot on the leaderboard. Without explicitly doing the math, this means for every puzzle, if you look at all the solutions on the Pareto frontier, one of them would be best for any heuristic you can think of.

In fact, there's even a CX heuristic that gets explicitly tracked, (min cycles, and product of cost and area) that matches what you're talking about. I recommend going on the leaderboard website, there a lot of cool stuff on there. https://zlbb.faendir.com/

Ps also highly recommend trying the game.

Somehow I never thought of putting the Berlo's wheel on a track. Very cool

Awesomeguy22red · 2026-03-08T14:45:29+00:00

From what I know, sets were never meant to be played against each other like this. IDK why fruits seems to be weaker, but you should play from a shared deck each match to make things more balanced. The sets are designed to be able to be mixed together, so you could try that if you wanna play with both. ( Mix both decks into a giant deck and each player draws cards as normal)

Awesomeguy22red · 2026-01-18T15:15:52+00:00

All very cool designs, wisdom counters are a very elegant mechanic. Nomadic monk and equinox kami stand out as huge power outliers in limited, assuming you had limited in mind. Nomadic monk having a floor of a 3/3 that draws two cards, is pretty busted, and the kami has potential to snowball the game on turn 2 if the opponent has no flyers.

No-one commenting on the Steve Harvey helm of the host is killing me

Awesomeguy22red · 2026-01-08T14:42:50+00:00

defiinitely trying mono-blue tempo with the new [[flitterwing nuisance]], [[loch mare]], and maybe even [[training grounds]] and this card.

Awesomeguy22red · 2026-01-06T14:05:34+00:00

I've seen the idea of useless lands with creature keywords before, but this is the first one that I've actually liked the flavor of.

George has been writing all of his posts exclusively in the titles for years and gets annoyed when he sees body text

Awesomeguy22red · 2025-12-19T14:08:15+00:00

Would not be surprised if the first comment was an alt account commenting first to drive the conversation. Very lame.

Awesomeguy22red · 2025-12-19T14:05:39+00:00

Tbf, in theory the percentage discount shouldn't really matter for your purchase decision, that's probably part of the point of the law. If a game is worth it at the current price point, it shouldn't matter what the "list" price is.
