About Idle Primes
Idle Primes is an incremental game with a horror story wrapped around it. You've always been obsessed with prime numbers, and now you're alone in your bedroom with a CD-ROM you shouldn't have found. You boot it up and start clicking primes.
The primes are your currency. You spend them on upgrades, automate the search and unlock new ways of finding them across the number grid. Meanwhile, the deeper you go, the more something on the other side of the screen pays attention to the room you're sitting in. The look is low-poly 3D in the style of the first PlayStation.
The developer ipip released it on Steam on 9 November 2026 for Windows, at £3.29. It has occult imagery but no combat.
Made with AI tools. The developer says they used AI for: writing.In their words: “The Steam page says generative AI helped translate the in-game text into other languages. The developer says the original writing, art and design are theirs or licensed.”
