The demo began with a very simple test displaying two strawberries. The game asked you to choose which of the lovely red fruits was being displayed in 3D. After selecting the left strawberry, which obviously was the correct choice, the camera pulled away and started rotating around the strawberries revealing that the one on the right was just a cardboard cutout. The cardboard cutout then fell to the ground allowing the real strawberry to show its superiority.

After the first challenge, the demo displayed a set of four more difficult challenges to choose from. The first one of these I tried out featured a mine cart and three sets of paths it could travel on. The paths popped out of the screen and were weaving in and out of one another. Only one of the paths led to a diamond and the game challenged you to choose the correct path. After choosing the correct one, the mine cart slid down the rail path and the camera rotated around the action.

The demo would only allow you to complete one of the more difficult challenges before ending, but I was able to try out the others. Fans of boxes of chocolates will be delighted to learn that the next demo featured one. There were six chocolates that you could observe in an open box and you needed to select the ones that were 3D. After choosing the correct ones the box was flipped onto its side and three delicious looking chocolates (I imagined they were filled with cherries) rolled out of the box and it became obvious that the other chocolates were simply painted on. I really enjoyed the reveal and thought it was a silly but effective display of 3D.

Another of the challenges featured two couples dancing. Similar to the other challenges, you needed to determine which dancers were in 3D. The two couples had a very cartoon-like look and they slightly looked like they were made of porcelain. In this one, the dancer farthest to the right was not in 3D.

The last challenge I faced was about golf. There was an overhead view of three golf holes and you needed to determine yet again which was 3D. The one farthest left clearly had depth and made this another easy challenge. After getting the correct answer, a 3D putter and golf ball dropped down into frame on the right. The putter lightly tapped the ball and it rolled over the fake golf holes and landed in the real hole.

3D challenge didn't seem like it would make a very fun game because almost all the puzzles were ridiculously easy. The only challenging one was the one with the mine cart. However, it could be a nice addition to a future title in the Brain Training series.
