Lost Secrets (Mysterious F2P)

I like some of the F2P games but inevitably, they always try to force you to pay. The puzzles are either very easy or designed to be so difficult and frustrating that you want to use a hint, but hints are always so expensive that you’d have to buy a pack of gems with no option to watch ads or gems acruing over time. Then, when you finally make it through the main game, you “unlock” the bonus game - but can’t play unless you pay for it! I’ll stick with Five-BN and other developers who give options to earn hints and let you play the bonus game you earn for free.
