Can my friends play my game before I publish it to Roblox?

Yes. PromptBlox shows a 3D preview of your game right in the browser. Anyone with the project link can walk around the preview — no Roblox account needed. This is the fastest way to get early feedback. You can paste the link into Discord, Messenger, or any chat app. The preview is not the same as playing on Roblox, but it shows the layout, theme, and 3D meshes so your friend can tell you if it looks good before you go through the publish step.

What is the difference between a public and private server on Roblox?

A public server is what most players play on — any Roblox user can join. Roblox automatically fills it with players who find your game on the front page. A private server is invite-only. Only people you give the link to can join. Private servers are perfect for playtesting with friends — no random strangers, no chaos. The server creator pays a recurring fee in Robux, set by the game owner. As the game creator you can make private servers free or pay-to-access.

How many friends can play together at once?

Roblox supports up to 200 players per server, but most games use a lower limit for performance. PromptBlox sets a sensible default based on game type. Obbies and adventures usually run 30 players per server. Paintball arenas can fit 30-40 since the maps are bigger. Tycoons and simulators often cap at 10-20 because each player needs their own plot. If you want to change the server size, you can adjust it in the Roblox Creator Dashboard after publishing.

How to Share Your Roblox Game with Friends

Q: How do I get the Roblox link for my game?

After publishing, go to the Creator Dashboard at create.roblox.com. Click your game in the Creations tab. The game page shows the link at the top — it looks like roblox.com/games/123456789/your-game-name. Copy that URL and share it anywhere. Anyone who clicks the link goes straight to your game. If your game is set to Private (not Active), only you can join from that link. Make sure to set the game to Active before sharing publicly.

Q: Can friends play if I am not online?

Yes. Once published and set to Active, your game runs on Roblox servers — you do not have to be online. Friends can join anytime, even at 3 AM. This is one of the biggest perks of publishing to Roblox: your game is always playable. PromptBlox preview links also work without you being online, but they only show the 3D world for walking around. To actually play the gameplay (jumping, collecting coins, scoring), the game needs to be on Roblox.

Three ways to get your friends into your game — from the PromptBlox preview to a private Roblox playtest. Pick the one that fits.

Sharing your game with friends is the best way to find out if it is actually fun. You will see issues in the first ten minutes that you missed after hours of building. This guide covers three ways to share, from fastest to most polished.

Pick the one that fits where you are in the build:

PromptBlox preview link — quick look, no Roblox account needed
Public Roblox game link — for the real playtest, anyone can join
Private Roblox server — friends only, no strangers

Option 1: Share the PromptBlox preview

The fastest way. Friends do not need a Roblox account, do not have to download Studio, and do not have to wait for you to publish. They can see your game in their browser in seconds.

Open your project in PromptBlox

Go to your project page. The URL in your browser is the share link — it looks like promptblox.ai/p/abc123.

Copy the URL

Click the address bar, copy the whole URL. Or right-click the project name and choose "Copy link."

Send it to your friend

Paste into Discord, Messenger, text message, or anywhere. When your friend clicks it, they see your 3D preview. They can rotate the camera and look around but cannot play the gameplay yet — that happens once you publish to Roblox.

TipThe preview is perfect for early feedback like "the candy zone looks awesome" or "zone 3 looks too dark." Use it before you spend time on publishing.

Option 2: Share your published Roblox game

Once your game is published and active on Roblox, you have a real game link anyone can click. This is the best way to do a real playtest with friends jumping in.

Publish your game

Follow the publishing guide to get your game on Roblox. Make sure to set it to Active in the Creator Dashboard or your friends will not be able to join.

Find your game on Roblox

Go to create.roblox.com and click your game under "Creations." Or search for your game name on roblox.com.

Copy the game URL

Your game URL looks like roblox.com/games/123456789/your-game-name. You can copy it from the address bar or use the Share button on the game page if you see one.

Send it to friends

Paste the URL into Discord, group chat, social media — wherever your friends hang out. They click, log into Roblox, hit Play, and spawn into your game.

Option 3: Run a private server

A private server is invite-only. Only people you share the link with can join. Perfect for playing with just your friend group, no random strangers.

Open your game on Roblox

Go to your game page on roblox.com. Scroll down to the Servers section — there is usually a tab for private servers.

Create a new private server

Click Create Private Server. Give it a name like "Friends Playtest." Private servers usually cost a small amount of Robux per month, set by the game owner.

Important: as the game owner, you can change this price or even make it free. Go to your game settings in the Creator Dashboard and look for the Private Server section.

Share the server link

Each private server has its own link. Copy it and send to friends. When they click, they go straight into the private server with you. You can also turn on "Friends Allowed" so everyone on your Roblox friends list can join automatically without a link.

TipPrivate servers are great for testing scary or weird games — your friends can react without strangers watching. They are also useful for streaming on TikTok or YouTube without random players hijacking the recording.

How to run a great playtest

Once your friends are in the game, here is how to get useful feedback:

Watch silently first. Do not coach them. See what they figure out on their own. If they get stuck, write it down and fix it after.
Ask "what was confusing?"not "did you like it?" The first question gets you fixes. The second gets you politeness.
Time them. How long did it take them to find the second zone? If it took 10 minutes, your obby is too hard. If it took 30 seconds, too easy.
Refine before the next playtest. Use the fix-a-broken-game guide to patch issues, then test again with a new friend.

Three things to send with the link

A link by itself is fine, but a link plus a little context gets way better feedback. Try this template:

"Made my first Roblox game! It is a [theme] [game type]. Should take about [time] to finish. Tell me what was hardest: [link]"

Example: "Made my first Roblox game! It is a candy obby with 6 zones. Should take about 10 minutes to finish. Tell me what was hardest: roblox.com/games/123"
