Reveal was insane! Summary:
Each house has a new action button power.
Stark can finish the current house mode with a direwolf once per ball.
Lannister can purchase playfield multipliers with gold, which time out eventually just like before. 500 gold per multiplier. Existing Max multiplier rules still enforced, based on houses completed. They also earn even more gold than before.
Baratheon can light a temporary Lord of Light save on both outlanes once per ball.
Tyrell can access Iron Bank once per ball at a greater value than before, and multiplied by playfield multipliers.
Martel is still add a ball once per ball.
Greyjoy doesn't change, but now you inherit the house action power of the most recent house you plundered.
Targaryen is now a playable house! They can pause all timers for 15 seconds once per ball. They also spot themselves as a completed house like Greyjoy, so you don't need to fight the dragons at all to progress.
Really cool changes that will make it easier to advance to Hand of the King and Iron Throne for sure.
You can also now complete the current house mode(s) by capturing a castle in the upper playfield.
Castle multi-ball has been revamped, and is easier to progress to. The castle shot is lit on a new ball entering the upper playfield for a short timer. If you hit the shot, you advance one level towards castle multi-ball automatically. New super jackpot collected at castle loop during castle multi-ball.
There will be some new callouts, but no new animations. New visual effects added also.
Random mode for selecting starting house.
Upper playfield now has playfield multipliers independent from the main playfield, and these stack together up there.
Baratheon target/spinner exploit tougher to exploit. Now spinner value can only be advanced to the number of houses you have completed.
You can purchase 3 of the new house action powers during spend your gold mode. Martel, Baratheon and I think Tyrell. Once you purchase a new ability, you lose your old ability. You can only ever have one action ability at a time.
More stuff too, but I'll let others chime in.
