Update: We checked for new 99 Nights in the Forest codes on March 11, 2026, but there were no changes.
99 Nights in the Forest is a survival horror experience on Roblox where players explore a dangerous forest, rescue missing children, and defend their camp from cultists and hostile creatures during the night. Gems (also called Diamonds) are the main currency used to unlock new Classes with unique perks and starting gear. Redeeming codes is one of the simplest ways to collect extra Gems early.
