Nut Bolt Sort

How to play

These rules match version 1.0.0. They are player rules only.

1

Move a nut

Tap a source bolt, then tap a target. Only the top nut moves. The target must be empty or show the same color on top.

2

Watch the move count

Each successful move spends one step. Clear every bolt before the count reaches zero. Extra remaining moves improve the star rating for that level.

3

Locked nuts

A locked top nut cannot move. Clear nuts above it first. The lock opens when a neighbor bolt is full and a single color.

4

Toolbox

A toolbox slot parks one top nut off the board. Tap the slot to store or retrieve. The toolbox is not an extra bolt, and it must be empty to finish the level.

5

Boosters and daily play

Undo reverses the last successful move and restores one step. Extra bolt adds one empty buffer for that run only. Hint highlights a legal pair and does not move pieces for you. Daily Bolts uses a tighter move limit and the date on your device. All of this stays local.
