In The Talos Principle 2, as you finish the main puzzles, you might come across something called Lost Puzzles. If you've just started playing and are wondering where to find these after you've cleared a zone, here's some help.

Understanding Lost Puzzles
Lost Puzzles are extra challenges that you don't have to solve to move forward in the game. They're hidden and harder than the main puzzles. If you're getting frustrated, it's okay to leave and come back later. Completing one feels like finishing a main puzzle because you get to activate a similar mechanism.

Finding Lost Puzzles
Keep an eye on the compass at the top of your screen as you wander around. It shows white question marks that point towards Lost Puzzles, as well as other secrets like Star challenges or underground labs. Look for a blue triangle on the compass—that means you're near a Lost Puzzle.

Also, check the island's map or the blue stones that give you hints to know how many Lost Puzzles are in that area.

Rewards for Solving Lost Puzzles
What you get for solving Lost Puzzles isn't immediately obvious. But as you play, you'll notice locked golden doors that seem to be connected to these puzzles.
Just like the first game had bonus levels, this one seems to have the same, possibly unlocking something big toward the end. But you'll probably only find out what that is later in the game.
