LOCATION UNKNOWN - June 2, 2026 - ipip today announced that the demo for Idle Primes, a horror incremental game about discovering prime numbers across expanding grids, is now available on Steam.
In Idle Primes, players begin with one simple instruction: click the primes.
Each discovered prime becomes currency, allowing players to buy upgrades, unlock automation systems, and develop increasingly strange methods for searching the grid. What starts as a clean number-clicking game gradually mutates into something larger, faster, and more unsettling.
Idle Primes blends satisfying incremental progression, minimalist interaction, mathematical discovery, and a creeping retro-futuristic horror atmosphere. The demo supports English, Spanish, Japanese, Korean, Simplified Chinese, Portuguese, and French.
