How it works

Tap a slot on the active row, then tap a side color.

Or just tap a side color to fill the next empty slot automatically.

The side palette stays visible while you scroll the board.

Use the eraser tool to remove colors quickly.

Feedback

Black peg = right color, right slot.

White peg = right color, wrong slot.

Peg order is only a summary. It does not map to exact positions.

Status

Colors stay on the side. Audio is initialized on tap, guesses auto-advance, and the cursor wraps to slot one after the last slot.
