Zoom changes the scale of page content; fullscreen gives the player more screen area. They solve different problems, and a game drawn inside a canvas may respond differently from ordinary text.
Check what actually grows
Fullscreen can remove surrounding browser interface without enlarging every button. Page zoom may enlarge the layout but leave part of a fixed-size player outside the viewport. Pinch zoom is another behavior and varies by device. Compare the controls and the visible play area after each change rather than assuming a higher percentage improves usability.
Try the steps
- Note the current zoom setting so you can restore it.
- Try the game's fullscreen button if available and inspect the entire board.
- If controls remain small, adjust zoom gradually and check that buttons remain reachable.
Should a website prevent zoom to protect the game layout?
No. People may rely on magnification to use the site. If controls become clipped, restore the previous setting and report the game, device and zoom level so the layout can be fixed.
