Idle games

Games that carry on without you, which on a phone means the tab you leave open and come back to on the bus.

Oredrift is ours: chip your way down through rock, hire a crew, and the crew keeps digging while you are asleep — then collapse the shaft on purpose and go deeper than you could have reached by hand. The choice it wants from you is when to throw away what you have built.

Idle Chop Miner and Alien Clicker Invaders are the straightforward version. Island Idle Survival and Object 73: Survival Clicker put a story on top of the same loop, and Real Estate Tycoon and Bitcoin Crypto Tycoon are the ones where the number going up is money. Be aware that a few games are filed here by their studio and are really arcade games with an upgrade screen.
