This is a very challenging logic game. If you consider the rules carefully, you can figure out exactly where each Atlantean will go before you choose your move. HOWEVER, this would take an enormous amount of time and really cut back on the fun. If you want to spend hours going over the logic to try for gold medals or don't care about the score, this game is for you. Even though the moves are predictable, the Atlanteans are very much 'lemmings' and will walk into certain death when you try to shepherd their neighbors to safety. This was more frustrating than fun for me.
