Pencil Icon Instructions

You will need a school-provided Google account (@lebanon.k12.or.us) to register. Personal Gmail accounts will not work.
 
Step 1: Register for an Account

Complete the following steps to register with the classroom arcade:

    • Go to arcade.mrhelland.com
    • Click Register (or Sign in with Google if that option is visible).
    • When prompted, sign in with your school Google account — it must end in @lebanon.k12.or.us.

Your account will show a pending status until it is approved.

 
Step 2: Wait for Approval

Your account must be approved by Mr. Helland before you can log in.

    • Check back at arcade.mrhelland.com periodically.
    • Try logging in — if your account has been approved, you will be taken to the site.
    • If you still see a pending message, check again later.

DO: Send Mr. Helland an email if you have not been verified within 24 hours

 
Step 3: Sign In
  • Go to arcade.mrhelland.com
  • Click Login and sign in with your school Google account or the username and password you created.
  • Once signed in, you will be taken to your home page.
 
Step 4: Choose Your Display Name

The first time you log in, you will be asked to choose a display name. This is the name other students will see on the leaderboard and in reviews.

    • You will see a list of 10 generated name options. Read through them carefully.
    • Click the name you want to use.
    • If you do not like any of the options, you may click Regenerate List — but you may only do this once.

DO NOT rush this choice — your display name is permanent.

Tip: After regenerating, you will not be able to go back to the original list. Choose wisely!
 
Step 5: Explore the Arcade

Take a few minutes to look around the site before submitting anything.

    • Browse the game gallery on the home page.
    • Play a game if any are available.
    • Check your profile and My Games pages.
    • Find the Submit a Game page — you will use it in the next steps.
    • Look at the Leaderboard to see how points are earned.
 
Step 6: Export Your GDevelop Game for the Browser

The arcade requires an HTML5 browser export — not the desktop or mobile version.

    1. Open your game project in GDevelop.
    2. Click File → Export.
    3. Choose HTML5 / Web (sometimes labeled Web (browser) or HTML5 game).
    4. Click Package. GDevelop will build the game and open a local preview in your browser — leave it open for the next step.
    5. Choose a destination folder and save the exported files there.

DO: Confirm that the export folder contains a file named index.html — the arcade will reject any ZIP that does not have one.

 
Step 7: Take a Thumbnail Screenshot

Your game needs a thumbnail so it looks good in the gallery.

    1. While the GDevelop in-editor preview is open, use the Snipping Tool (Windows key + Shift + S) to take a screenshot of the game window.
    2. Open Paint (or any image editor) and paste the screenshot.
    3. Crop it so only the game is visible — no title bars or browser chrome.
    4. Save the file as thumbnail.png.
    5. Place thumbnail.png in the root folder of your export (the same folder that contains index.html).
Tip: If thumbnail.png is inside your ZIP, the arcade will use it automatically — you will not need to upload it separately.
 
Step 8: Create Your ZIP Archive

You need to compress your exported game files into a single ZIP or 7Z archive.

    1. Open your export folder. It should contain index.html, thumbnail.png, and several other files and folders.
    2. Select all of the files and folders inside the export folder.
    3. Right-click the selection and choose Compress to ZIP file (Windows 11) or Send to → Compressed (zipped) folder (older Windows).
    4. Name the ZIP after your game — something like PlatformPlayhouse.zip.

DO NOT: ZIP the export folder itself — select the contents of the folder, so that index.html is at the root of the archive, not buried inside a subfolder.

Tip: You can double-click the ZIP to verify that index.html appears immediately when you open it, not inside another folder.
 
Step 9: Submit Your Game

To submit a game to the arcade, you will need to do the following

    1. Click My Games in the navigation.
    2. Click Submit New Game
    3. Fill in the Game Title and a Description (at least a sentence or two about what your game is).
    4. Select a Genre from the dropdown.
    5. Click the Game ZIP upload area and choose your .zip or .7z file. (You can also drop files in this area)
    6. If you did not include a thumbnail.png inside your ZIP, upload a thumbnail image using the Thumbnail upload area.
    7. Click SUBMIT GAME.

Your game will be reviewed before it is published in the gallery.
You will be able to see it in My Games with a status of unpublished until it is approved.

Extension:
