The tabletop-games-inspired mobile game studio and development partner

Greener Grass Company was formed around a shared passion for games in 2015. We have combined our skills and experience to develop work-for-hire games and prototypes while building our self-published empire of tabletop-game-inspired digital games.

We are always ready to “grow your game” as long as we click and share the same values. Meanwhile, we nurture our two mobile dice games, Dice Hunter: Quest of the Dicemancer and Golden Roll: The Yatzy Dice Game, that are out on iOS and Android, and look forward to soft-launching our third digital dice game.
