@RedMaverickZero: The way I see it is not every gamer has the same thought process or the same capacity to solve certain puzzles. When creating a game one should consider their desired audience, not only the age group of their desired audience but also their level of puzzle solving capacity, race, background and any other thing that could come in to play to either make or break their experience. Referring specifically to the Zelda series, many of the puzzles are extremely difficult for many gamers. There are lots of walkthroughs online explaining certain dungeons and a lot of conversation between gamers discussing how certain things can be solved. I consider these types of games the perfect amount of challenge for me, others may find them too easy and some may give up early in the game.
Perhaps the best thing to do is first establish an audience that you want (in my own game I am creating an experience for gamers like myself, with a specific sense of humour and at a puzzle hardness level that feels difficult for me).
Next I think it is important to try and build up the skills needed to help the gamer succeed at harder puzzles. For example have the gamer learn how to solve puzzle type A, then puzzle type B, then puzzle type C. After they learn the key skills through a combination puzzle type ABC at them and they should be able to solve even though it might take them some time to apply all the skills together.
For Pepsi's particular case this type of learning is not so easily accomplished. I think the puzzle laid out by Pepsi is about as simplified as it can be, this type of puzzle is just generally a challenging one. I think since it seems to be trial and error based, the puzzle should eventually become apparent to the gamer. Since this is an optional level in the game I would think there would be an option to "give up" and continue with the main game though which would be good because then Pepsi's game allows for a wider range of audience which is another good option. In fact Zelda games do this to an extent too, you can play the main game which is fairly difficult or you can challenge yourself to solve all the additional puzzles, get all the heart pieces which can require more advanced problem solving skills, do the minigames, etc...
I'd like to hear what others think on this topic too.
