Embed Game Size It Up
A small daily challenge for your game portal, classroom or website.
Add the playable game
Copy this iframe into your page. It includes the complete game, touch and keyboard controls, and measurement sources. No account or download is needed.
<iframe src="https://gamesizeitup.com/embed" width="100%" height="720" style="border:0" allowfullscreen title="Game Size It Up"></iframe>Keep the attribution link visible and clickable. Please retain “Play on gamesizeitup.com” inside the game. Do not crop, cover or remove it. It opens the original game in a new tab.
Choose a mode
The default is daily: five shared comparisons, refreshed at midnight UTC. Add a mode parameter to the iframe URL for another game.
| Mode | Iframe URL |
|---|---|
| Daily challenge | https://gamesizeitup.com/embed?mode=daily |
| Unlimited practice | https://gamesizeitup.com/embed?mode=unlimited |
| Scale Streak | https://gamesizeitup.com/embed?mode=streak |
| Geography | https://gamesizeitup.com/embed?mode=geography |
Fit your page
The game fills the iframe width and adapts to mobile screens. Start with a height of 720 pixels; the frame can scroll when a measurement reveal needs more room. For automatic height changes, add this optional script after your iframe:
<script src="https://gamesizeitup.com/embed-resize.js" defer></script>The script verifies the message origin and sending frame before adjusting height. No game answers or saved progress are sent to your website. Progress stays in the player’s browser when storage is available; browser privacy settings can prevent embedded progress from being saved.
Link to the original
Only the dedicated /embed page supports third-party embedding. To share a standalone game, link to the daily challenge, Unlimited or Scale Streak.
