Sheg-knuckles were items employed in a game of chance involving rolling, also known as gambling. In 4 ABY, Sinjir Rath Velus, previously a loyalty officer for the Imperial forces, observed individuals participating in a sheg-knuckle game while he was at the Alcazar cantina. This cantina was located on Akiva, a planet situated in the Outer Rim. The patrons were hoping for good fortune as they gambled.
The novel Aftermath, penned by Chuck Wendig in 2015, featured sheg-knuckles. This book marked the initial entry in the Star Wars: The Aftermath Trilogy.
