Server health

From a live sample of 6 servers taken 2026-08-19. Roblox returns a page of servers rather than all of them, so these describe the sample.

Space available Sampled servers averaged 46% full.

Server size: 14; players per server
Typical fill: 46%; 0 of 6 full
Median ping: 154ms; High latency

Passes & prices

5 passes for sale, 98 Robux to 973 Robux. Prices are our last observed Roblox listings; confirm the price in-game before buying. Roblox does not publish how many have sold, so this is a price list, not sales or earnings.
