The Category filter organizes drills into eleven skill-based groups. Each category targets a distinct area of billiards play. The descriptions below explain what each category trains and why it matters.
| Category | Description |
|---|---|
| Aiming | Ball pocketing from a variety of distances, cut angles, and pocket types (side and corner). Fundamental to all billiards play. |
| Banking | Bank shots with single and multi-rail variations. |
| Transition | Pocket the object ball and land the cue ball in a specific target zone. Transitions combine aiming, speed control, and cue control, making them among the most challenging drill types and essential for high-level play. |
| Breakdown | Pattern Breakdown drills are a sequential set of Transitions packaged as a runout scenario. They carry all the challenges of Transition drills. |
| Kicking | Kick shots with single and multi-rail variations. |
| Safety | Hide the cue ball or a key object ball to leave your opponent a difficult or indirect shot. Safety play is a critical skill at the advanced level. |
| Pattern | Run a sequence of balls, attempting to clear the table. Patterns can be played in Open style (any ball order, more accessible) or in game-specific styles: 8-ball, 9-ball, and 14.1 (progressively more demanding). |
| Cue Ctrl | Control the cue ball to follow a desired track using English and follow/draw, combined with accurate reading of carom angles off the initial object ball contact. Cue control is essential for proper leaves and for breaking out trouble balls or clusters. |
| Speed Ctrl | Practice calibrating your stroke speed against the speed scale used in ICA Aiming Ball indicators. One drill type is available in this category. |
| Games | Drills structured around game formats rather than isolated skill practice. |
| Various | Drills that do not fit a specific skill category, including image-based drills (JPG or PNG format) that ICATS EZ cannot automatically classify. |
