Idle CPU

Empire-building at silicon scale: you start with one tiny chip and a single core, and the endgame is a giant AI data hall. Idle CPU is a tech tycoon idler where your rig serves AI requests and turns every finished token into cash — cash that buys the upgrades that serve requests faster.

The management is balance, not just growth. Six stats compete for your money — cores, clock, memory, cooling, power and uplink — and the rig only runs as fast as its bottleneck, so the skill is spotting which one is choking the glowing stream of requests and fixing exactly that. Raise the clock, beat the heat, feed in more power: the classic overclocker's triangle, kept deliberately calm.

Progression has a map and a cast: jobs for 25 quirky clients pay the way up a site ladder — chip, board, rack, row, data hall — with every site after the chip adding its own twist, from network links to solar power. A Lab researches lasting boosts, collectible crew and AI model cards speed the rig and raise your pay, and the prestige loop is thematic: train the next model, restart stronger, push further.

It keeps the idle contract properly: progress continues while you're away, with offline earnings to collect, plus daily rewards and quick goals for short check-ins, all in calm neon. Reception is middling so far (3.8 stars at 10K+ downloads), and no purchase or ads terms are stated in the listing — but for tycoon fans who enjoy bottleneck-hunting more than button-mashing, the theme alone is a breath of fresh air.
