CushionSystems app analytics for March 19

An app for browsing and learning the billiard cushion system. Among the cushion systems, we are collecting systems that are likely to be used frequently in pocket billiard games. You can learn each system in a quiz format. The billiard table diagram shows the start and finish positions, so use the system calculations to answer the correct number. Questions of various patterns are randomly asked, so you can learn the cushion system efficiently. The quiz has a challenge mode that aims to answer all the questions correctly and a time attack mode that shows how many questions can be solved in 60 seconds. The purpose is to learn the cushion system, but you can also enjoy it as a brain teaser. (Since it is a game for learning system calculations, scratches etc. are not considered.)
