99 Nights in the Forest is a Roblox survival horror experience developed by Grandma’s Favourite Games, where groups of players build a campsite, defend it through the dark, and work to rescue four missing children from a cursed forest. Diamonds are the primary currency for unlocking character classes, and the codes below offer a direct way to stock up without grinding.

Other Ways to Earn Diamonds
Codes are the fastest route to free diamonds, but several in-game systems reward them as well. Common, Legendary, Cold, Ice, Iron, Good, and Gold Chests can all drop diamonds when opened. Surviving past day 50 and completing the full 99 nights each grant a bonus, and earning in-game badges also adds to your total. Combining code redemptions with these milestone rewards is the most efficient way to accumulate currency for new classes.
Where New Codes Are Announced
Grandma’s Favourite Games releases codes around major updates and game milestones, roughly every few months. The official 99 Nights in the Forest Discord server is where new codes tend to surface first — the announcements and updates channels are the ones to keep an eye on. The developer’s YouTube and X accounts are also worth following for early drops.
