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): 0.71/day in the week to Sep 11 → 4.14/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.

Adorei o simulador; ele tem um enorme potencial. De fato, quanto mais próximo da realidade estivermos, melhor, pois, apesar de existirem outros simuladores de circuitos elétricos profissionais, pagos e gratuitos, este é, sem dúvida, um dos melhores. Como ponto positivo, destaco a possibilidade de simular sistemas com alto grau de realismo. Como ponto negativo, menciono a quantidade limitada de componentes, como relés e PICs, mas não encaro isso como um grande problema, já que é possível esboçar a ideia inicial e, com algumas adaptações e criatividade, fazer bastante coisa. Sei que estou exigindo muito, pois, pelo que entendi, o desenvolvedor atua sozinho. Outro ponto forte foi a inclusão do Arduino; isso foi fantástico! E sim, vale muito a pena adquirir. I loved the simulator; it has enormous potential. Indeed, the closer we are to reality, the better, because, although there are other professional electrical circuit simulators out there, both paid and free, this one is, without a doubt, one of the best. As a positive point, I highlight the ability to simulate systems with a high degree of realism. As a negative point, I mention the limited number of components, such as relays and PICs, but I don't see this as a major issue, since it is possible to sketch the initial idea and, with a few adjustments and creativity, do quite a lot. I know I'm asking for a lot, since, from what I understand, the developer works alone. Another strong point was the inclusion of Arduino; that was fantastic! And yes, it is definitely worth getting.

While it is still under development, this is the best breadboard simulation I have found. I'm looking forward to Crumb V2 to be released!
the update is looking good, can't wait to try it :D
can we add sparks and arks and stuff like that for like people who like people like electroboom and styropyro otherwise very good game good job
more 74xx need
Gostei muito, deu para simular algumas coisas e em 3D ficou bastante legal pela visibilidade porém não dá para deixar de perceber que sim existem coisas que faltam como alguns sensores e atuadores, talvez mais opções de montagem, mesmo assim achei legal
Ey estoy muy alegro de que este programa exista, siento que es muy interactivo y visualmente bonito, ademas lo utilizaré para un proyecto inicial de universidad y será muy buena idea implementarlo, sigan así que su labor es muy agradecida
Necesito que agreguen el integrado AD620 para controlar niveles estandar de voltaje y corriente
Looking forward to V2.0
I bought it a while ago, and now I finally decided to give it a try... I was disappointed. Game looks nice graphically, but that's about it. This game is more like a demo than a full simulator. The Arduino emulation is poor, and in many cases, the Arduino behaves in a way that doesn’t match reality. Additionally, the 3D view only distorts the perspective. It’s more of a toy for kids to learn something than a full-fledged simulator. There are much better simulators on the market - ones that are free and work more like they should in reality. P.S. And the selection of available components is very limited.
