Three of the game puzzles were hard. I had to guess half of the answers for two of these puzzles. I had to watch walkthrough for the third hard puzzle which is a word puzzle. I had an idea how to solve it but I didn't have the energy to solve it after being stuck on the other puzzles. I love tricky puzzles when they don't stop me from enjoying the game and when they are made fairly for the target group. Tricky games like this are more suited for teens and older.
