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. Features: • Multiple buildings to choose from • A complex game that’s easy to learn and hard to master • Idling mechanic that allows you to earn resources even if you are offline • You have the first map for free, the others need to be unlocked • Multiple upgrades to choose from • Interesting gameplay mechanics that you have to keep an eye on at all costs • Stellar research system

Take command of the host's cellular defences and fight back -- organ by organ, system by system -- in this handcrafted strategy game that brings the hidden battlefield inside every living creature to your fingertips. 25 LEVELS ACROSS 5 WORLDS Journey through the beetle's body, from the haemolymph to the neural cluster. Each of the five worlds introduces a unique environment with its own strategic challenge, requiring you to rethink your approach at every turn. 5 UNIQUE MECHANICS Master Armoured Nodes that resist attack, Flow Channels that accelerate unit movement, Linear Pathways that constrain your routes, Signal Relay chains that extend your reach, and Multi-Map battles that split the fight across interconnected zones. DEEP DEFENSIVE UPGRADES Upgrade captured nodes through four tiers of defence. Hold your ground, build your forces, and time your upgrades to turn the tide. Every decision matters -- overextend and the fungus will reclaim what you fought to protect.

Verdict
The clearest difference is in-app purchases: Cell Conquest at none against Reactor Idle Tycoon's 10. Cell Conquest also leads on ads (none vs shown) and update cadence (weekly vs every 4 months). On price, device support and iOS requirement there is nothing between them.
