Use this mat to see the groups and regrouping. You may hide it on smaller screens.

Algorithm Lock

Tap the glowing box, then use the number keyboard. If regrouping is needed, fill the small carry box too.

Tap box → number. Use the in-game keyboard so iOS and Android screens stay stable.

Progression: 1d × 1d facts → 2d × 1d no regrouping → 2d × 1d regrouping → 3d × 1d no regrouping → 3d × 1d regrouping → 3d × 1d = 4d.
