Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 2.29/day in the week to Sep 10 → 5/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About

Sums Steam only; Xbox, GOG publish no volume signal, so the true total is higher by an unknown amount.
Updates
Build ids and update times come straight from Steam's PICS — the same source SteamDB reads. Patch history grows as we record new builds.

If the glass bead game was real: ALSO OPUS MAGNUM DLC IN THE BIG 2026 ARE YOU KIDDING ME

One of the best puzzle games I've ever played. I still can't believe they put out a DLC 8 years later and its just as good as the base game. Lots of player made puzzles in the workshop too.

It's a Zachtronics game, and if you know that name, then you already know what you're getting into. If that name *doesn't* mean anything to you, then it's best described as a tightly knit puzzle-solving game based on developing iterative programmatic solutions using a largely visual, object-based 'language'. And the puzzles start off simple enough, but evolve into elegant brain-teasers over the course of the game. The best part though, is that once you've developed a solution, you then get to see (roughly) how it compares to the rest of the world, and exactly how it compares to any of your Steam friends that have also solved it! It's one hell of a carrot on a stick that inspires you to tweak and improve your solutions even though you've already cleared the hurdle to move on to the next puzzle.

Большую часть времени играл в саде Сигмара
Exelent game! It's about geometry puzzles and syncronization, simple, but has some deep interesting puzzles on the extras. Dificulty: 4/10 Optimized dificulty: 6/10

Went in, tryied to make an efficient system. "Oh I think I can make it one cycle quicker". One hour goes by, whole machine redisigned, and the process is indeed one cycle shorter. 10/10 would optimize again.
this game really makes me think, it's an amazing puzzle game for late night unwinding
