Fornite Season 5, Week 10's challenges are now live and you can find a full breakdown of what they involve here. Along with the details on what each of the challenges involve, there's a guide on how to complete the "Search Between Covered Bridge, Waterfall, and 9th Green" in the paid Battle Pass tier. However, in the free section there's also one challenge that requires a bit of legwork, which we've already done to save you some time and effort.

The "Search Jigsaw Puzzle Pieces in Basements" challenge is pretty self-explanatory, but given that the very large Fortnite island has quite a few basements for developer Epic Games to hide jigsaw puzzle pieces in, a little guidance can go a long way.
