Start Point Swap

Endpoint Swap

Exchanges the positions of two same‑colour endpoint pairs (start and end nodes) on the board. This rearranges the puzzle layout, often making a previously difficult connection more straightforward without changing the colour pairing itself.

Note: all drawn paths are cleared when a swap occurs. Use at the start of a level or after a path reset. One swap per purchase.

Swap is applied instantly. The new layout remains solvable.
