About Left Justified Studio & Prolific Games

At this company, we believe tabletop games are just about the most fun you can have with your family and friends. 

The Prolific Story

Prolific Games was founded by Bill Sininger in 2010 with the publication of Flapjacks & Sasquatches. He was joined later by partner John Harris.

Together, Bill and John enlivened regional and national conventions from Twin Cities–based Con of the North to international mega-con Gen Con, publishing new games like Witch Slapped and expansions like Cup of Joe. Their goal was always creating and teaching games that deliver fun for every player.

By 2020, Bill and John yearned to return their focus to their families and full-time careers. They arranged to sell Prolific to Midwest-based game industry veteran Jeff Tidball, a fellow traveller of many years. The opportunity dovetailed with Jeff’s experience at publishers including Atlas Games and Fantasy Flight Games, his desire to spend more time working for himself, and his steadfast belief that games are just about the most fun you can have with your family and friends.

I Made a Game! (Or, "Partnerships with Designers and Other Publishers")

Game designers, we love you. We got into this business because we love game design and publishing more than anything.

Prolific Games — and the other Left Justified Studio imprints — are always interested in bringing great new games to gamers. If you have a game design you’d like us to consider publishing, sign up for our newsletter and watch this space. We’ll post more specific information soon.

 In addition to licensing designs for publication, we’re interested in


  • Licensing English language / North American distribution rights for games first published elsewhere in the world
  • Working with indie designer-publishers who’ve Kickstarted games but aren’t interested in selling and promoting them forever
  • Purchasing outright existing companies whose catalogs align with our plans and beliefs

If you’d like to talk to us about your existing title or catalog, email Jeff Tidball at jeff at left dash justified dot com. Let us know what magnificent things you hope we can accomplish together.
