Putter King is Japan's ﬁrst indoor miniature golf franchise. We recently released a 3D miniature golf game app for the iOS entitled Putter King Adventure Golf (Android version coming soon). The app has been well-reviewed by gaming sites such as TouchArcade and AppCraver. On our website, we are hosting a miniature golf hole design contest. The winners of the contest will get their designs featured in the Putter King app.
