TL;DR
In 1x1 mode, one visible center color is hidden. In 3x3 mode, only one visible corner is
shown and you infer the sticker color that points away from you. In both cases, the displayed colors
and answer buttons follow your selected cube orientation.
What You See
1x1 mode uses a center-only cube representation and applies one of the 24 whole-cube
orientations.
3x3 mode applies a 30-move random scramble and isolates one visible corner, leaving only
its two visible stickers on the screen unless you turn Centers on for extra reference.
Your job is to infer the hidden sticker color from what remains visible.
Why This Helps
On a normal cube, two visible stickers constrain the third sticker on that piece.
Practicing both center inference and corner inference builds faster color recognition so
you stop consciously reconstructing the cube and start reading colors immediately.
How to Use It
- Choose 1x1 or 3x3 mode, then press Start.
- Look at the two visible colors on the rendered cube.
- Choose between the two opposite-color buttons shown underneath the image.
- Repeat until you can identify the hidden color immediately.
When 3x3 centers are enabled, Neutrality controls which orientations can appear and
Corner Position can lock the visible corner to DFR, UFL, or UBR.
Keybinds
On desktop, the left and right answer buttons show their current keybinds while the
trainer is stopped. Click either button to remap it. On phone, keybind remapping is hidden.
Timer Mode
Enable the timer before starting if you want session pacing. The trainer will show total
time and average time per attempt underneath the score.
