How to get more Diamonds in 99 Nights in the Forest

Available on Roblox, 99 Nights in the Forest has become a popular game among players who love challenging enemies in a survival-crafting setup. The rules are simple: Survive for 99 in-game day-night cycles and find four missing children to win. 

As easy as the plot sounds, you’d need to build a strong defense to tackle the perils, which in turn requires you to focus on upgrading your class. And for that, you need Diamonds, the main in-game currency of 99 Nights in the Forest.

While you can farm Diamonds in the game by completing challenges and opening chests, the currently active 99 Nights in the Forest code “afterparty” gets you 15 of them for free right off the bat. Besides the free route, you can also purchase Diamonds with real money.
