Utopia Engine is a great solo game that has a lot of replay value. We also love that it is free and easy to take along when we go out.
Shay's full review
I was looking around at print & play games on BoardGameGeek when I found this game. It seemed a little daunting to have a 12-page rulebook for a paper and pencil game, but I was intrigued. The instructions are written very clearly and are easy to follow. After two games, I put them aside and was good with just the adventure pages.
The story of the game is that you are trying to construct a device, the Utopia Engine, to stop doomsday. First, you have to find the parts in six areas and then you must assemble them before the world ends. You use two dice, a pencil, and some basic math to find and assemble the parts.
I love a good solitaire game, especially if it includes dice, and this game does not disappoint. I made a laminated copy and we have it with some other favorite print & plays to break out when we are looking for some quick fun.
