Island

A broad mix. Survival games where the island is the threat, treasure hunts where it's a resource, expansion games where you grow it, and hidden object scenes set on one. The setting is the common thread rather than the genre.

Hidden Objects: Island. There is nothing chasing you and nothing to manage - you search a detailed scene for items at your own pace, which is about as low-pressure as it gets.

Yes, Survival Island is exactly that. You are stranded with limited resources and the game is about staying alive long enough to make the place workable rather than escaping it immediately.

The opposite of a survival game. Instead of being trapped by the coastline you push it outward, growing the island as you go, which turns the setting from a constraint into the thing you're building.

Most do. They run in a mobile browser the same as on desktop, and the tapping and dragging these games rely on suits a touchscreen at least as well as a mouse.
