Questions

Can I join these from Cross-play?

Yes, from either. Every server on this page accepts Java and Bedrock clients, which is what cross-play means here. The two often use different ports, and each listing shows both addresses.

How many Unstable Cross-play Minecraft servers are listed?

28 right now. A combination only gets its own page here once at least 3 servers match it, which is why there is a page for this one and not for every pairing – the rest of the Unstable listings are on the Unstable page, and the rest of the Cross-play ones on the Cross-play page.

How do I join a server in Minecraft?

Copy the address from the server's listing. Java Edition: 1. Open Minecraft – Launch Minecraft: Java Edition and go to the Multiplayer menu. 2. Add the server – Click "Add Server" and paste the address into the server address field. 3. Join – Click "Done", then double-click the server to join. Bedrock Edition: 1. Open Minecraft – Launch Minecraft (Bedrock Edition) and go to the Servers tab. 2. Add the server – Scroll down, tap "Add Server", then paste the address and port. 3. Join – Save, then tap the server to join. Bedrock and Eaglercraft entries show their own address where they differ.

Do I need to own Minecraft to join these servers?

Most need a paid (premium) Minecraft account. Some run in offline mode, often called cracked, so any username can connect without buying the game – use the Cracked filter to find them.

How does voting for Minecraft servers work?

Voting pushes a server up this month's ranking and usually pays you a reward in-game – most listings show exactly what you get. You can vote once every 24 hours per server.

How is the ranking calculated?

Servers are ordered by votes received in the current calendar month, which resets on the 1st. Sponsor slots and premium plans buy visibility, never rank – they apply no boost of any kind, and every listing is ranked by votes alone.

Are these Unstable Cross-play servers free to play on?

Yes – every server listed here is free to join. Some sell optional cosmetic or convenience perks on their own store; look for the tags and reviews on each listing.
