The direct answer
Blind but Dangerous has no private servers and no VIP servers. The experience-level setting is off, so there is no button, no price, and no link that opens a private session.
How we know
The official games API for universe 10771991516 returns createVipServersAllowed: false in the November 3, 2026 snapshot. That field is the platform switch for VIP server sales; false means the creator has not enabled them.
A private-server list endpoint also exists, but it requires a login and returns an authentication error in this environment. That error is not evidence of absence; the setting above is the evidence.
Public servers and the 8-player limit
Public servers are the only way to play. Each holds up to eight players. In the November 3 snapshot, the first ten public servers were all at 8 of 8 players, which shows how quickly a popular server fills.
That snapshot is a moment, not a rule. A server can empty after a round ends, and a new one can open at any time.
How to play with friends
There is no invite-only room and no queue or reservation documented. The practical route is to agree on a server and join at the same moment; if it fills, try the next one. Expect some attempts to miss during busy hours.
About 'free private server' links
The game does not sell private servers, so a page that offers a free private-server link is not describing an official feature. Do not enter your Roblox password or a session cookie on those pages. The same warning applies to 'free Robux' offers.
If you want a quieter group, the official Discord is the verified community channel. It is a chat server, not a private game server.
What could change
The creator can enable VIP servers in a future update. Until the game page shows that option, the answer on this page stands. Re-check after a major update rather than trusting an old screenshot.
