Puzzles these days a little too easy for you? Don't have enough of a headache when you're finished with one? Longing for something with pieces that look like they lost a fight with a pair of rampaging scissors? Not anymore! Plexus and SmartKit present three puzzles designed to challenge your eye. Rotate the pieces to make them fit and try to think outside the box as you solve these three different themes.

I/O is a brain-teaser of a puzzle game along the lines of the fabulous Click Drag Type series that comes with no instructions. Use your skills of discovery, intuition and creative problem solving to figure out what must be done to arrive at a solution.
