Do you want to create your own reactor and generate energy for an entire country? Or maybe you want to harness the electric power and sell it for a profit? Reactor allows you to do that and so much more in one of the most intense and one of a kind strategy games that you have ever played. The premise in Reactor is very simple, you have to create power plants and generate as much electricity and heat as possible all while keeping everything under control and converting it into a lot of money. You will have to start off easy, with the help of small wind turbines that will generate a little electricity, enough to get your business going. Then you have to focus on getting stuff like offices and more turbines, solar panels, generators, coal burners, and in the end you will have the ability to create your own reactor, be it a nuclear, thermonuclear or fusion reactor, something that is very important to keep an eye on. Reactors are by far the best if you want a great return on investment but they are also the less stable and you have to manage heat as they can easily become unstable. With more than 10 maps to unlock and play, you will always have your hands full as you will try to figure out the best way to make insane profits and obtain a stellar result. You can play it safe and run a business that brings less but stable amounts of money, or you can check out alternative methods that are riskier but with a better return on investment. Reactor is an astounding idle game, one that manages to bring in front extraordinary gameplay moments and stunning opportunities. It’s very fun to play and you can easily use it as an idle game, because resource production will take place even as you go away, which is even more exciting. In Reactor you have all the power in your hands and it all comes down to you to make the right choice and take this one of a kind gameplay mechanic to new heights. With incredibly fun gameplay, nice mechanics and interesting choices, Reactor is the ultimate game that you want to play. A sheer combination of strategy, idle gaming and perfect unlock system, Reactor will help you spend your time wisely with amazing moments and a stellar outcome.

Sehr schade finde ich aber einige Features im Spiel selbst: 1. Das große Forschungszentrum ist meiner Meinung nach erst zu spät erreichbar 2. Die kleine Bank ist zu schwach für ihr Auftreten 3. Nach einigem Spielreseten für die extra Boni ist das Spiel viel zu schnell durchspielbar. (Es lässt sich ab einem gewissen Punkt in nicht mal 10 Minuten durchspielen) Meine Vorschläge an die Entwickler: 1. Das mittlere Forschungszentrum an den Wärmekraftreaktor packen und die Upgrades von 25% auf 30% steigern um kleinere Forschungszentren zu steigern. 2. Die kleine Bank stärker machen, so statt 30-50 Mal mehr als vorher zu 100fach stärker 3. Den Steigerungsfaktor von 4fach auf 1,5fach oder 2fach senken, damit man mehr vom Spiel hat. ### 2/5 — I love this 'frame' of game *2026-05-10, version 1.77.01* From power n chill on roblox, back when they were barebones. and the one on kongregate ### 1/5 — Reprise sympa mais rendue injouable par la pub. *2026-04-30* Reprise de jeu flash (le principe de faire progresser) plutôt sympa, ergonomie simple mais parfois lourde vu le nombre d'objets à faire défiler et progresser. Dommage qu'il ne prenne pas en compte l'orientation (horizontal/vertical mais aussi haut/bas). L'omniprésence de publicité rend le jeu peu jouable. ### 3/5 — Perca de progresso *2026-04-29* Se trocar de dispositivo vai perder todo o progresso do jogo ### 4/5 — Can’t 100% *2026-04-06, version 1.77.01* Unable to get every achievement without spending real money. One achievement requires the purchase of the cash island. ### 3/5 — Game Plateau’s off in the latter end *2026-04-01* Hello, the game is interesting so far however, my one complaint is that the game plateaus off once you reach the arc reactor and the small bank because there isn’t any support for the battery. Every other facility has upgrades . Game cannot progress plus i notice at times my dollar amount decreases randomly. ### 1/5 — Let me pay for ad-free! *2026-02-28* The forced ads are really making this game unplayable. At least let me pay money for an ad-free experience. ## Frequently asked questions about Reactor Idle Tycoon ### What is Reactor Idle Tycoon about?
