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 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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.

Reviews
Fun and engaging puzzle game. Mechanics are simple yet complex in a way that reliably scratches the brain. Difficulty curve is somewhat strange, especially after the second section, but overall very fun. 9.5/10, like any other Zachtronics game.
barely scratched the surface yet but this is already one of my favorites. It's very intellectually stimulating and the puzzles are immensely satisfying. That word "satisfying" has gotten watered down lately to basically just mean "nice" these days, but I really mean it. I do one puzzle, I refine my design a little more, and I feel satisfied, and I set it down for the night while also looking forward to doing the next one tomorrow. In a world full of things that demand your constant endless attention, it's so great to find a game that both has longevity and feels like it respects your time. It feels good for my brain in more ways than one. EDIT: i first wrote this after only ~3 hours. i just beat the main story after ~30 hours, and I look forward to the bonus puzzles as well as going back and driving myself mad optimizing my designs. boy this is fun

Thumb up
nice
very good game
amazing
very good tutorial and I like how the story is folded into the puzzles but you don't have to pay attention to the story
I'm changing my review. Although I recommend this game, the lack of UI scaling is a terrible thing. The game won't let me switch to other apps while it's loading which is a most unfriendly behavior. And there is no "full screen windowed" mode like so many other games. If I were able to give stars, i would go with 3.5 or maybe 4 out of 5 stars because of the lack of UI scaling and the unfriendly startup screen. There are also some essential editing tools, like mirroring selections, that would be easy to program and yet were not added. I also, and this is a personal preference, dislike that there is no single overall score. But it is fun to try to get all three score values above "average".
