Elemental

You build a camp, keep the campfire burning, and try to reach 99 nights. The official listing says you build that camp with friends. A run can continue past night 99. Rescuing four missing children is a major objective, and a Self-Preservation badge is described for reaching day 99 without rescuing any of them.

Yes. You can start a run alone. Survival parties are reported at up to five players. That party size is separate from whatever capacity the Roblox lobby shows.

Diamonds are the class currency. The September 3, 2025 class guide says you earn them from badges, events, and chests, then spend them in the class shop. Promo codes are another reported source.

No confirmed developer Discord invite was tied to the Roblox group from the public pages read here. Use the Roblox experience and the Grandma's Favourite Games community linked on the game page.
