Power-up Pixel Flow

Saving a run when two useful pigs are about to arrive but the five slots are already tight.

The board is still closed and you cannot immediately use the extra slot.

Using it before the opener color is visible.

Removing one wrong pig so the real opener can enter the tray.

Several slots are bad. Hand fixes one problem, not a full queue collapse.

Using it on an annoying pig instead of the pig blocking the next clear.

Recovering a matching board where you know the next needed color and the belt will not serve it.

The board is still blocked. Shuffling before opening space usually changes nothing.

Treating Shuffle as a solver instead of a queue reset.

Pushing through a large blocker after you confirm it is the real route opener.

You have not identified the blocker that unlocks the rest of the board.

Spending it on scattered pixels that normal ammo can clear.
