I’ve been playing (the browser/PC incremental game about optimizing heat and energy) for a few months now, and I have to say — the r/reactoridle community on Reddit completely elevated the experience.
Even though the game hasn’t updated in a while, the sub keeps getting new players discovering it. The “Post your idle layout” threads are still getting replies in 2025. That’s a sign of a quality game and a quality subreddit. reactor idle reddit

Unlike many idle game subs that are just “look at my big number,” r/reactoridle is full of people sharing actual layouts, discussing ground heat vs. water pumps, and debating whether capacitors are overrated. You’ll see heatmaps, efficiency calculations, and clever compact reactor designs.
If you play Reactor Idle — or even if you’re just into Factorio, Mindustry, or optimization puzzles — go join r/reactoridle . It’s one of the most helpful and underrated gaming subs I’ve ever come across. Zero drama
