TL;DR

Practice 2-sided recognition with four modes: Pre-AUF, Select by Name, Verification (confirm), and Verification (predict). Select by Name shows case buttons under the cube, while verification modes show a 3D Before and After image around the main cube so you can compare your expected result quickly.

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. Pre-AUF mode: Recognize the case and select the needed AUF (↑/←/↓/→)
4. Select by Name: Identify the case and click its case button. For F2L, OLL, and PLL you can also answer from the keyboard with the matching number or letter combinations.
5. Verification (confirm): Perform the algorithm, compare your result to the shown After image, then press Yes/No (Yes gives +1)
6. Verification (predict): Decide whether the shown After image is correct; about 50% of rounds are intentionally wrong
7. Reset: In verification modes, Reset returns Before to solved and rebuilds After from solved + current algorithm chain

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
