Begin with the right series
Game of Thrones is the 2011 series. Its page contains the seasons and the checkpoint form. If you arrived looking for Flixgo Game of Thrones season 4, season 5 or season 8, you do not need a different show entry for each one. Open the series and choose the season you are following.
Keep a spoiler-free reminder
Use the last episode you completed, not the episode you hope to watch next. Select a season, enter the completed episode number and save the checkpoint. A return visit in the same browser displays that reminder. It does not read your activity on another service, so update it after watching.
Prequels have their own pages
House of the Dragon and A Knight of the Seven Kingdoms are related series, not ninth or tenth seasons of Game of Thrones. Their casts, episode lists and viewing choices stay separate.
To watch Game of Thrones, set your viewing country and choose Watch now. Check that the destination offers the season you want. A listing for the show does not by itself confirm that every season is included in every edition.
For another long-form adventure afterward, browse fantasy series. For a more contained evening, try the Middle-earth films.
