I thing to note about their half price double ticket days is they choose what games they want to do it on. Not all games are double ticket and not all are half price so games like Crossy, Quik Drop, Power Roll are normal priced unlike Langers which you visited as well where all games are half price which also overlaps which double tickets! Also since your visit they added Over The Edge and Fantastic Prizes to this location!
This Beaverton KingPins was weird. Crossy was not half off. The Crossy at the Portland location was half off on Monday evening. I don’t understand why some games are and some aren’t half off.
