Gaddis Gaming TableTopper 2.0 launches on Kickstarter
The fantasy of turning any surface into a proper gaming table has haunted game players for decades, with many trying and few succeeding to fill that niche in the marketplace. Enter: Gaddis Gaming and the much-improved version 2.0 of its much talked-about TableTopper.
First we should note that the TableTopper is not a table, we assume you already own one. It is a topper – lightweight and portable – that can easily turn your unsatisfactory table into a gaming surface that is just the right size for any game you are playing. It’s expandable and retractable, so one purchase allows you the versatility of a 4’x4’ or 4’x6’ play area. It’s modular, making it easy to transport and store or to increase the length to 8’ or 10’, if you are so inclined. And it is customizable with an assortment of colors and finishes, logos and designs to decorate the sturdy Out-Of-Play areas.
The best news of all is that the Gaddis Gaming TableTopper is currently available on Kickstarter at a special low price. Check it out: https://www.kickstarter.com/
