Requires Internet Access
The latest release (version three for 2014, simply called Puzzler World) requires internet access to even launch, making it useless when WiFi isnt around (which is usually when I play Puzzler World versions one and two). Also they changed it so you need to constantly purchase new puzzles rather than just pay once for a mega-pack. Stick with 1 and 2 if you have them.
