Third-party Modules
Practice programs created by respected pool instructors and professional players, such as Tor Lowry, Phil Capelle, Earl Strickland, and Dr. Dave Alciatore. These modules take proven systems from books and videos and turn them into on-table exercises using ICATS, so learning happens through real practice.
Some modules focus on one skill, like safeties or banks, while others combine skills such as shot-making, cue-ball control, and pattern planning. Many include instructions and companion videos. The goal is focused, intentional practice that builds skills you can actually use in competition.
