TL;DR

Practice 2-sided case recognition by identifying the correct AUF (adjust U face) needed for different algorithm categories. The trainer shows a scrambled state where you must recognize which case you have and determine the correct pre-AUF needed before executing your solving algorithm.

Settings

• Bottom Color: Select the bottom face color for your preferred cube orientation
• Front Color: Choose which face should be in front
• Algorithm Set: Choose from various algorithm categories (F2L, OLL, PLL, ZBLL, etc.)
• Cases/Subsets: Filter by specific cases (F2L, OLL, PLL) or subsets (ZBLL T1-T6, U1-U6, ZBLS Case 01-41, COLL/2GLL T,U,L,P,H,S,A) when available
• Animation: Control when solutions are shown (never, when incorrect, always, or AUF only)

How to Use

1. Configure Settings: Select algorithm set, cases/subsets (if available), colors, and animation preferences
2. Edit Algorithms: Customize which algorithms to practice using the "Edit Algs" button
3. Start Training: Click "Start" to begin showing random cases
4. Recognize the Case: Study the 2-sided view to identify which algorithm case you have
5. Determine AUF: Choose the correct AUF (or no AUF) needed before executing your algorithm
6. Answer: Click the AUF button or use keyboard shortcuts (↑ for No AUF, ← for U, ↓ for U2, → for U')
7. Review: Check your answer with color-coded feedback and optionally review previous cases

Algorithm Management

Use the Edit Algs button to customize your practice session. If you're logged in, you can filter by algorithms marked as known or learning. For algorithm sets that support it, you can also select specific cases or subsets to focus your practice (e.g., individual PLL cases like "Aa Perm", T cases for ZBLL, or specific case ranges for ZBLS).

Tips

• Case Recognition: Focus on identifying cases quickly from the 2-sided view
• AUF Prediction: Learn to anticipate the needed AUF based on case recognition
• Case/Subset Practice: Use case or subset filtering to focus on specific case groups you want to improve
• Review Mode: Use "Review Previous Case" to study cases you got wrong
• Keyboard Shortcuts: Master the arrow key shortcuts for faster input
• Color Neutrality: Practice with different color schemes to improve recognition skills
