The goal in the first version of Enigmo was to get liquid dripping from one area of the puzzle into its respective container in another area of the puzzle. To accomplish this, you could use several different objects like drums to bounce the drops, platforms to guide them or sponges to soak them up and re-route them down into their containers. By the time you solved the puzzle, you would have drops flying all over the place in an insane juggling act.
The basic goals remains the same in Enigmo 2, but this time around, there are not only liquid drops but lasers and plasma drops as well with each behaving in different ways. You can even manipulate the effects of gravity by activating gravity reversing switches, or using objects that have their own gravitational pull to alter the projected path of drops. These new elements add another dimension to Enigmo's challenging puzzles.
Speaking of new dimensions, Pangea Software has made the puzzles in Enigmo 2 all 3D. Unlike the first release of the game where you only had to direct the droplets left, right, up and down, Enigmo 2 has you trying to solve puzzles in 3D space making things much more fun and challenging.
Enigmo 2's touch controls are well executed. I would have figured trying to move the camera around and accurately placing objects in 3D space using only the iPhone's touch screen would have been a nightmare. Thankfully, Pangea made it all too easy. To pan around the puzzle in 2D space you just drag a finger on the screen; to manipulate the view in 3D; you just drag two fingers.
When it comes to placing objects in just the right spot, all you have to do is tap a part of the puzzle; then when you place your next object, it's automatically lined up with it. Once you've put an object in play, a circle appears around it that you use to rotate it. If you touch the circle and drag it out, it becomes bigger for fine-tune adjustments. A quick double tap will send the object back to the toolbar at the bottom of the screen where the other objects reside. Along the right side of the screen is another toolbar with buttons to undo, snap to grid, and switch back to the default camera view.
