Devil’s Jazz Tycoon

Hell, it turns out, runs on per-second profit margins. Devil's Jazz Tycoon is an idle tycoon game where you're the new boss of the underworld's business empire — starting small at the Devil's Crossroads and unlocking location after location, each one paying out more than the last, all dressed in cabaret style with jazz on the speakers.

The loop is the genre's classic three gears. Tap your locations to earn cash directly; upgrade every building to grow its income and plan the order of upgrades as strategy; then hire demon managers to take over locations and automate them, so the money rolls in without your finger.

On top of cash sits the prestige-flavored currency: souls. The more money you earn, the more souls you receive, and each soul grants a profit bonus that compounds the whole operation. And the empire doesn't clock out — your demons keep earning while you're away, so returning means collecting whatever Hell made in your absence.

It's free to play, small (10K+ downloads) and sits at a middling 3.8 rating — the machinery is the familiar idle-tycoon engine, so the purchase here is purely the flavor: stylish demon characters, a smoky cabaret vibe and jazz where other tycoons put clipboards. If the theme makes you grin, the tapping will follow.
