Blast through asteroids, drill down to a planet's core, then fire the engines and fly on to the next system. This idle space game keeps mining while you are away, so coming back always means a pile of resources and a fresh round of drill and ship upgrades. Simple numbers-go-up comfort, free in your browser with nothing to download.

Run a little inn that only takes monster guests, and give each one the room it actually wants. Read their habits, match them to the right space, then furnish it well enough that they leave happy and pay for the privilege. Rooms are limited and every visitor has opinions, so the fun sits in deciding who gets what. Free to play in your browser, no download needed.
