What is WBT game mode?

The World Bowling scoring system, described as “current frame scoring,” is used during the stepladder finals of the World Bowling Tour Finals. Current frame scoring counts 30 pins for each strike (regardless of previous shot), 10 pins for each spare (bonus pins that are added match the first roll of the next frame), and basic pin count for open frames. The tenth frame follows the same format as the first nine frames. That means no bonus, or fill shots, are given. The maximum score is still 300, achieved with ten rather than twelve, consecutive strikes. World Bowling scoring is intended to be easier to understand than traditional scoring for fans or bowlers that are new to the sport. The television networks also advertised current frame scoring to increase struggling television ratings.
