How to Publish a Game on Roblox: Complete Guide (2026)

Your Game Is Built — Now What?

You've spent hours (or minutes with AI tools) building your Roblox game. Now it's time to publish it on Roblox so the world can play. This guide covers every step from first publish to getting your first players.

Step 1: Publish from Roblox Studio

Open your game in Roblox Studio
Go to File → Publish to Roblox (or Ctrl+Shift+P)
If it's your first time, click "Create new experience"
Enter a name and description
Click Create

Your game is now on Roblox — but it's private by default. Nobody can find it yet.

Step 2: Configure Game Settings

Go to the Game Settings menu (Home tab → Game Settings) and configure:

Basic Info

Name — keep it catchy and descriptive (under 50 characters)
Description — explain what your game is, include relevant keywords for search
Genre — select the closest matching genre

Permissions

Set to Public — go to Game Settings → Permissions and change from Private to Public
Enable playing — make sure the place is set as the start place

Age Rating

Roblox requires experience guidelines. Go to the Creator Hub and complete the questionnaire for your game. This determines who can see and play your game. Be honest — misrating can get your game moderated.

Step 3: Create a Game Icon

Your game icon is the first thing players see. A great icon dramatically increases clicks.

Size: 512x512 pixels
Format: PNG or JPG
Tips: Use bold colors, show key gameplay, include your game's name in large text, avoid clutter

Upload via Game Settings → Basic Info → Icon.

Step 4: Add Thumbnails

Thumbnails appear on your game's page. You can add up to 10.

Size: 1920x1080 (16:9 ratio)
Show gameplay — players want to see what they'll experience
First thumbnail matters most — it's shown in search results

Step 5: Write an SEO-Friendly Description

Your description helps players find your game through Roblox search:

Start with what your game IS in one sentence
List key features with emojis for scannability
Include keywords players might search for
Add update notes to show the game is active
Include social links (Discord, Twitter) for community building

Step 6: Get Your First Players

Publishing alone won't bring players. You need to promote:

Share on social media — TikTok, YouTube, Twitter, Reddit
Post on Roblox forums — DevForum and community Discord servers
Ask friends to play — initial player count helps with algorithm visibility
Use Roblox sponsored experiences — paid promotion within the Roblox platform
Create a YouTube video — gameplay trailers attract players

Step 7: Keep Updating

The algorithm favors active games. Regular updates signal that your game is worth recommending:

Add new content weekly or bi-weekly
Fix bugs players report
Respond to feedback
Add seasonal events
