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/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.

I love it. I keep coming back to it after tinkercad. but CRUMB game has alot to do. But definetly worth purchasing.
Absolutely Amazing. I've been building an 8 bit computer and loving it.
아이싯펄 전력조절 존나 귀찮네 ㅋㅋ + 아잠만 이거 왜 복붙안되냐? 이러면 64bit full adder 만들려는거 ㅈ되는데;; 찾아보니 CRUMB 2.0 무료로 대규모 업데이트 할꺼같은데 부탁드립니더

Yea so this and volt sim are my go to software for when a guy get real lonely. 10/10 please make half boards and please allow multiple PSU connections to board thank you!
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!
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.
Para aquellos entusiastas de la electrónica, aunque sea a nivel básico, sirve mucho para profundizar pequeños conceptos de la electrónica y sus ramas de la misma. Aun así, debo decir que existen otros simuladores que puedo recomendar tanto de pago como otros que no que son muy buenos para profundizar y experimentar a mayor profundidad los conceptos de la misma; por ejemplo, Proteus, EasyEDA, CiruitLab (Este es online), entre otros. Igualmente volviendo al punto, este simulador es recomendable si y solo si quieres aprender de lo básico haciendo algunas cosas complejas, pero sin llegar al nivel de profundidad o de variedad que te ofrecen los otros simuladores antes mencionados.
Great program! Rough controls and small learning curve at first but once you get the hang of it it's great.
Пишу коментар 15.04.2026 Поки що гра ще недопрацьована, але для аналогових схем цілком підійде, навіть можно робити прості схеми з ардуино нано та тфт дісплеями, але при умові що вони будуть дуже простими. Я намагався зробити осцилограф, сидів 4 дні - нічого не вийшло, уперся в логіку самого симулятора. Якщо симулятор буде і далі розвиватися, то через роки 2-3 буде топ.
I really like CRUMB, it has a lot of potencial! Hello Mike, I just discovered CRUMB and I just got in love with it, I like electronics as a hobby, learning bit by bit about them and I dreamed to have a simulator like CRUMB for years, I am pleased you are creating such a wonderful tool to learn and experiment with electronics. I am very interested into creating electronic solutions with my own taste related to electric guitars, amplifiers, sound efects and speakers, I hope CRUMB will be my main tool to experiment in that regards. Keep making CRUMB an amazing virtual electronic laboratory! ːsteamthumbsupː
