Running a review game when the wifi dies

The projector is on, the class is seated, and the game will not load. Everyone has had this lesson. It is worth being precise about what actually failed, because the fix is different for each cause and only one of them is about your school's internet.

What usually breaks

The connection is there but useless. This is the common one. The signal bar is full, the page half-loads, and nothing finishes. Shared school bandwidth at 9am is not the same resource it was at 6am when you tested.

The page loaded but the pictures did not. A game that opens as text with blank rectangles where the artwork should be. Almost always the images were still downloading when the connection gave out — the page arrived, its contents did not.

Nothing loads at all. The honest case. No connection, no fallback, no lesson.

The habit that fixes all three

Open the game the night before, on the device you will teach from, and save it.

Not a browser bookmark — a bookmark is a promise to fetch the page later, which is exactly the thing that will fail. A saved game keeps the page and everything it needs to draw itself on the device, so opening it in the morning touches the network not at all.

In SlideQuest that is the Save for offline button on any game, or Download all from Games on this device, which takes the whole library in one pass. Saved games survive updates to the site and stay until you remove them.

Test it the way it will fail

The mistake is testing while connected. Everything works when the network is there; that tells you nothing.

Turn the wifi off on the device, then open the game. If it opens with its artwork intact, it will open in your classroom. If it does not, you have found that out on a Sunday evening rather than in front of thirty learners.

Have a version that needs no screen

ReadFive review formats that survive a noisy classroom

Even a perfectly prepared device fails sometimes — a projector bulb, a power interruption, a room change to somewhere without a socket.

The cheapest insurance is knowing which of your questions you could ask out loud. A Rapid Fire round needs a voice and a board. A Family Feud round needs a voice and chalk. If your review plan collapses entirely without a screen, the plan was about the screen.

What offline does not give you

Saved games play; they do not sync. Scores from a game played without a connection are not recorded anywhere, and a game you edit offline is edited on that device only.

For whole-class review, none of that matters — the score is on the board and the class is in the room. It matters if you were expecting a record afterwards, so it is worth knowing before you plan a lesson around one.
