this is not a mechanical puzzle


when I first got this puzzle I was extremely satisfied until I started playing with it. It is not a puzzle. It is pretty much just a lock with 180 million combinations. Don't blow 250 dollars on this thing

From Marbles:

Fun and full of adventure.

Best Puzzle I Ever Did


I'll be honest, I'm sure most people aren't going to believe my post. When I scroll through reviews, I usually see the really good reviews and think people made them up. In complete honesty, I'm not making this up. I'm not going to fool anyone into buying something that isn't worth it. If you enjoy puzzles and making your mind think differently then what you're used to, this is definitely a puzzle for you. The people that are saying this is nothing but luck to solve, are wrong. It is possible for someone to get lucky and open the ISIS without knowing what they did, but there is an actual way of solving it. Inside, there is a pellet like ball that you must move through the maze inside. While you can't physically see the track and drop holes, you can listen and hear the ball. You need to visualize what is taking place inside to be able to solve it the right way. This is the easiest one of the series, and trust me when I say it will make you want to continue in the series to open the rest in this puzzle adventure.
