I like brain games, and this one has a lot to choose from: memory games (like Concentration), harmony (music note repetition), language (like Scrabble), logic (Sudoku), observation (hard to describe), and intuition (Minesweeper). In some of the games, I did just fine, but others, like the observation games, were more challenging. Not everyone likes, or is good at, every kind of brain game. And that's the problem, here. You have to complete all puzzles in order to finish the game and solve the riddle of the cube. But Help simply has basic instructions, and there are no hints if you get stuck during a puzzle. I got stuck in the first observation puzzle where you have to find some way to turn on a grouping of lights in a sequence so that they all stay lit. Well, it wasn't working for me, and there were no hints to help out. So right away I'll never be able to finish the game because I don't know how to get past that one puzzle. True, you can simply do the puzzles you like and not worry about solving the riddle of the game, but then why buy the game? The game lost points because the lack of hints will set some players up to fail. And it has nothing to do with I.Q. Some people are just better at certain games than others!
