99 Nights in the Forest is a Roblox survival horror experience where players must endure 99 nights in a cursed, closed-off forest while searching for four missing children. A monstrous Deer and the cult that worships it stand in your way, making every resource count. Diamonds are the premium currency here, spent on character classes that improve your starting stats and gear. The codes below let you grab free diamonds and other rewards without any extra grind.

How to use the “yay fishing” code
Unlike the standard codes, yay fishing cannot be entered through the lobby menu. It only activates during an active session while you are actually fishing.
/ to open the in-game chat, type yay fishing, and hit Enter. Two diamonds will be added to your total right away.Other ways to earn diamonds
Beyond codes, diamonds drop from Common, Legendary, Cold, Ice, Iron, Good, and Gold Chests. The game also rewards bonus diamonds for surviving past day 50, completing day 99, and earning certain in-game badges. Natural diamond income is slow compared to codes, so redeeming every available code early gives you a meaningful head start on unlocking stronger classes.
