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): 0/day in the week to Aug 1 → 0.14/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 2,400 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.

2021 update: Just played the game again after the updates. It worked very well and was able to play with an opponent. The new superposition moves make more sense and the merge function is interesting. The developer has been working hard at this and I hope the gaming and quantum community will support him. 2019 Review: I cannot praise this game enough. The concept and the probabilities introduced to chess make it very interesting. It makes one have to think through not only the strategy in chess, but in the probabilities as they stack up with quantum moves. It allows one to split a piece into many probabilistic pieces where it is not certain which piece wins or dies. Outstanding implementation by the developer. My only suggestion for the developer is to work on the online game to make sure it doesn't keep crashing. I have not been able to play the online game from beginning to end without one of the players disconnecting. Keep up the effort. Thanks.
in the current version the tutorial breaks the game

Really great game. So much fun. Since I am writing on my master thesis in QFT at the moment, this is a fun way to show off and talk to everybody on my floor in the university.
As someone who has an obsession of quantum mechanics, this game is amazing. The only downsides are that it is still in alpha and has some bugs, but it is definately worth the ten dollars. More people should buy this game to fill up the servers and give the developers more incentive to get it out faster.

very good
Really great idea, so much potential. I really wish for more players trying it out. Go watch "Anyone can Quantum" with Paul Rudd and Stephen Hawking as a kind of intro!
I could give this game a 10/10 or a 9/10 for a few bugs. Let’s decide with a particles spin. Now it’s in a superposition of alive and dead Particle observation 10/10 would half kill king again
