As of December 2013, SJ3 is no longer shareware and no new registrations are available. SJ3 is antique software and it is distributed as freeware. You can download a full freeware version of the game with all the features of the former full registered version.

Again; a huge thanks to all the wonderful people who took a little time and money to register the game back in the day. Your support was very much appreciated!
