Netslide

A pipes puzzle with a twist: you cannot turn the tiles, only slide whole rows and columns until every pipe connects.

A little time to think

Slide whole rows of pipes until one network lights up.

Your goal

Connect every tile into one network that reaches the source in the middle, with no loose ends. Tiles never rotate: each move slides a whole row or column one step, and the tile pushed off one edge comes back on the other. Connected tiles light up as you go.

How to play

Tap an arrow at the edge of the board to slide that row or column the way it points. Turn on Mark mode to slide in the opposite direction. Keyboard: arrows move the marker around the edge, Enter slides. Type changes the grid size.

Tips

Work outwards from the lit source: once a row is right, slide it only to move a tile through it and back.
Sliding a row all the way around brings it back, so a slide in the wrong direction is never lost. Undo is quicker, though.
Dead ends are the easiest clues. A tile with one opening can only sit where a neighbour points into it.

Use the board’s Type menu to choose a size or difficulty. Undo and Redo let you explore. Solve reveals the answer when you choose it.
