Underhearth

Underhearth - Play Idle Game
Idler, Incremental, MMO, RPGUnderhearth is an idle dungeon MMO played in the browser. Combat is asynchronous by design, not by compromise: every decision — gear, potions, tactics, who fills the empty slots — happens before the descent. A deterministic engine then fights it out tick by tick and produces a reproducible report you can re-run, share by seed, and argue about.The guild keeps records. Your deeds fill a public register, your standing earns you warrants, and the wall remembers who stayed down there. Levels run warmer the deeper you go; the one cold room is the wrong one.Every number is balance-tested: 10,000 simulated runs per cell, walls that keep tankless parties losing, and a published exhibit fight (seed 42) where the tank dies at tick 51 and the party still wins at 53.No real-time combat, no purchasable power — ever. Free to play, and playable without an account.

Stargazer

You inherit your grandmother's mountaintop observatory — tap catch stars streaking across a real J2000 night sky, trace actual constellations to fill her half-finished journal, and let your instruments generate Starlight while you're away. No spaceships, no sci-fi: just a quiet mountain, real astronomy facts behind every discovery, and a sky that becomes a genuine star map as you play. Prestige ("New Horizon") sends you deeper — from naked-eye constellations to the Solar System, deep-sky clusters, and exoplanets, each leap revealing older starlight.
