Embed SejrBank on Your Game Site

This page is about SejrBank, the old game, which stays embeddable as it was. Going Concern, its relaunch for a professional audience, ships as a self-contained build on request (mdf@sejr.com).

SejrBank is a free HTML5 banking simulator: a tycoon/strategy game where players build a bank from one branch to a global giant. You are welcome to put it on your game portal, blog or school site. Embedded players start instantly as guests: no sign-up, no login screen.

Option 1: embed code

Paste this where you want the game:

<iframe src="https://sejrbank.com/embed/" width="1280" height="800"
  style="border:0;max-width:100%;aspect-ratio:16/10;height:auto"
  allow="fullscreen; autoplay" allowfullscreen loading="lazy"
  title="SejrBank, the banking simulator"></iframe>

Option 2: HTML5 package

For platforms that need an upload (itch.io, Newgrounds, Game Jolt and similar): download the package, upload the zip as an HTML5 game, and set the viewport to 1280 × 720 with fullscreen enabled. The package is the complete game in about 320 KB with index.html at the root. It makes no network requests, has no links out and no login: players land on the career screen and their progress saves in the browser.
