Sandbox games give you a world and tools and let you decide what to do with them. There may be no goal at all, or goals you can ignore. That covers falling sand toys with hundreds of elements, voxel worlds you can dig and build in, scenic places to drive around and survival worlds you shape yourself. They reward curiosity: try something, see what happens, try something stranger.
