Our First Game

Rang Rivals — Court Piece & Hokm Online

Rang Rivals is a competitive four-player online card game inspired by the wider Court Piece and Hokm family of partnership trick-taking games, also known in different regions by names and spellings such as Rang, Rung and Kot Pees.

Two teams compete at one table using a standard 52-card deck, with trump selection, trick-taking and team strategy at the heart of the experience. Rang Rivals is being developed for Android with online multiplayer competition between real players.
