Nice Game Hints, as a website, serves players with low spoiler gradual hints. Having hints on the site is one way to help players. But there are far better options. Over the years we have developed several services for game developers.
For point and click games a great option is an in-game hint system. The player does not have to leave the game to get a hint on a puzzle.
This website is optimized for hint giving. But some developers might want to provide their own single page HTML guide. You can use Nice Game Hints editor to build that website.
Companion apps are perfect products for adventure games. The app can contain all kinds of content that goes hand in hand with the game's story.
