In the first season of Game of Thrones, Cersei Lannister warned that, “when you play the game of thrones, you win or you die.” The HBO series will end this year in its eighth season, meaning we will soon know who ends up on the Iron Throne (if anyone) and who dies trying.
In anticipation of the end, we went back to the beginning of the series to score how the houses progressed season by season. We included every Westerosi house which (at some point) held a wardenship or (at some point) sat on a throne… foreign or otherwise.
The houses were given points for every living character loyal to them. They received an additional point if those characters possessed magic. They also gained a point for every army they controlled. Bonus points were awarded if a house made progress from the previous season or if they did something awesome (like killing an annoying child king). No house has scored higher than twenty throughout the series so far.
