Sometimes it's hard to see the wood for the trees — but in the case of this optical illusion, it's a single leaf that's proving elusive.
Released to mark Earth Day this weekend, the puzzle challenges eagle-eyed players to spot the oddly shaped leaf in the tree's bright green foliage.
Its creators at switchmybusiness.com say they included one leaf shaped like a "foot" in the "ocean" of leaves on its branches, to highlight how important it is to be aware of the footprint we leave on planet Earth.
So can you spot it?
