Common problems
The game closes when I click somewhere else
That is how popups work in Chrome. Every move is saved, so the next click on the icon carries on where you stopped. To keep the game open beside the page you are reading, open Settings, then Open the game in, and choose Side panel or Tab. The choice applies from the next click.
I can't find the icon in the toolbar
Click the puzzle-piece icon at the top right of Chrome, then the pin next to Play Sudoku. Right-clicking the icon also offers Options, which opens the game in a tab.
There is no Side panel in Open the game in
Some Chromium browsers have no side panel for extensions. In those, the game opens in the popup or in a tab.
My games or statistics are gone
The game keeps your games, statistics and settings in this browser on this computer, and sends them nowhere. Another browser or another computer has its own. Removing the extension deletes its games, and clearing the data of sudokuhub.page deletes the games played on the site. We have no copy to bring back.
My progress from Telegram isn't here
The game in Telegram keeps its own progress, which follows you to all your devices. The extension and the game on this site keep theirs in the browser. They share no games or statistics. To play with your Telegram progress, open @sudoku_hub_bot.
The game says "Sudoku is open elsewhere"
The game runs in one place at a time on a device, so the one opened last takes over: a second tab, the popup or the side panel. Your game continues there. Press Play here to bring it back.
There is no sound, or the music is too loud
In Settings, Sounds and Music each have a switch and, while on, a volume slider of their own. They set the game’s own level, not your computer’s. Check too that the computer and the tab are not muted.
Does the extension work offline?
Yes. The extension holds the whole game, so it opens and plays with no connection, the hint and the daily puzzle included.
The hint is used up
Each game has one hint. It shows the next step and names the technique behind it. The next game has a new one.
