TL;DR

You're shown the top side of a 3x3 cube. One sticker will light up, and a move sequence will be given. Your goal is to identify where this sticker ends up. To mark a sticker, hold down on the top side sticker and drag to the correct side (or click to mark the top sticker).

Instructions

The 2D cube face in the trainer represents the top layer of a 3x3 cube.

Once you press "Start", a sticker will turn yellow and you'll be presented with a sequence of moves. Determine the final position of the yellow sticker after the sequence.

To select a sticker: press down your mouse/finger on the top sticker and drag to the side to choose orientation. Drag away to cancel. Clicking selects the top sticker.

NB: The move sequence might temporarily move the sticker out of the top layer, but the sequence will always end with the yellow sticker in the top layer.

Settings

• Type: Choose between tracking corners or edges
• Moves: Set sequence length (1-20 moves)
• Move Sticker Every Turn: Toggle to force the highlighted piece to move on every move of the sequence.

How to Use

1. Click "Start": Begin the tracking game
2. Track the displayed sticker: Note the yellow-highlighted piece and follow it through the move sequence
3. Mark where it ends up: Press down on the top sticker and drag your finger to the correct side (or click if it stays on top)
4. Get feedback: Green for correct, orange for correct position but wrong orientation, red for incorrect
5. Repeat: New case automatically generates from the correct answer position

Tips

• Start with shorter sequences and gradually increase difficulty
• Practice both corners and edges separately before mixing
• Visualize cube rotations in your head rather than tracing with your finger
• Longer sequences improve your ability to track complex piece movement patterns
