About Q Skill Challenge
This is an app for managing the records of the Hopkins Q skill Challenge Rating System for billiards games.
Cue skill level is determined for each rack, and you can see your billiards level in real time.
There are 7 levels of level judgment: ``Recreational Player, Intermediate Player, Advanced Player, Developing Pro, Semi-Pro, PRO, Touring PRO'', but the position within each level is divided into 5 levels and displayed in more detail.
Normally, 1 game consists of 10 racks, but you can also select a simple mode where 1 game consists of 5 racks.
About Hopkins Q Skill Challenge Rating System
This is a game designed by American pool player Allen Hopkins to judge billiards skills.
One person uses 15 balls to judge skill by scoring points using rules that are a combination of bowllerds and 9-balls.
The rules are simple: Drop the remaining 5 pieces from the play regardless of number, and then drop the final pieces in numerical order. If you make a mistake, it will end prematurely. Balls in the first half are worth 1 point, but balls in numerical order are worth 2 points. If you win all of them, you will get 20 points per rack.
Usually, 10 racks are considered as one game, and billiards skill is judged by the total score of 5 or 10 games. This app uses average scores, so you can easily judge your skill regardless of the number of games you play.
