Browser Compatibility

Lesix Games runs in a web browser. There’s nothing to install on your computer or your students’ phones.

Supported Browsers

Any current version of Chrome, Firefox, Safari, or Edge works. Keep whichever you use reasonably up to date — the platform relies on modern web features, and browsers more than a couple of years old may behave oddly.

If you have a choice, Chrome or Edge on the teaching machine tends to give the smoothest experience with fullscreen and multiple displays.

Requirements

Three things must be enabled. All three are on by default in every mainstream browser:

JavaScript. The entire platform is JavaScript. With it disabled, nothing loads.

Cookies. Used to keep you logged in. Blocking them means being logged out constantly, or unable to log in at all.

Pop-ups from Lesix Games. The display screen and the payment portal open in new tabs or windows. A blanket pop-up blocker will silently prevent both.

Extensions That Cause Problems

Browser extensions modify pages before the platform loads, and a few interfere:

• Ad blockers and privacy extensions can block the connection that keeps screens in sync
• Script blockers (NoScript, uMatrix) break the platform outright
• Dark mode extensions can make the display screen unreadable on a projector

If something behaves strangely, test in a private/incognito window — extensions are usually disabled there by default. If the problem disappears, an extension is the cause. Re-enable them one at a time to find which.

Two Different Browsers Is Not a Problem

You can run your control screen in one browser and the display in another. They sync through your account, not through the browser.

Some instructors do this deliberately — control screen in their normal browser with all their tabs, display in a clean second browser with no bookmarks bar or extensions.

Private/Incognito Mode

The platform works in private mode, but you’ll be logged out when you close the window. Fine for a one-off on a shared computer; inconvenient as a habit.

Student Devices

Only Pollster involves student devices, and the voting page is deliberately simple — it works on any phone browser from the last several years. Students don’t need a specific browser, an account, or an app.

Keeping Current

If you hit an unexplained problem, updating your browser is a reasonable first move. Most browsers update automatically; a browser that’s been open for weeks may be running an older version until restarted.

Next Steps

• Game Not Loading — when a page won’t open
• Sync Issues — when the display stops updating
• Display Setup — projector and screen configuration
