Grouping

Shape the sheet into the same groups you use while memorizing.

Group sizes describe how wide each group is. Separate alternating sizes with commas; for example, 3,2 repeats groups of three and two.
Choose whether the groups continue sideways or downward.
Each group spans this many adjacent rows.
Boxes enclose every group; dividers mark only the boundaries between groups.

Cursor highlight

Choose how much context follows the active digit.

A complete sequence highlights one full repetition of Group sizes.
Highlight color
The lighter shade shows the rest of a complete group sequence.
Advanced reading order

Use these options only when your natural starting corner is different.

How this layout reads

Seconds before the memorization sheet appears (0–60).
