The Talos Principle series, wala syang hard math aspect pero puro logic puzzles sya and maraming mga secrets na pwedeng madiscover.
Maganda rin yung The Witness, walang hard math din pero puro puzzle and minsan kailangan mong mag notes dito sa sobrang daming puzzles na pwede iapply sa other puzzles. Warning lang if color deficient ka, may color puzzles sa game na to.
