Connect the Pipes 2d

Connect the Pipes 2d is a flow puzzle that asks you to cover the whole board, not just join the dots. Every colour has two endpoints and you drag a pipe between them, but a solution only counts when no square is left empty, so a direct route that leaves gaps is the wrong route. Boards grow from small grids you can read at a glance into layouts where you have to plan the long, winding path for one colour before drawing any of the others.

This title is best suited to players who enjoy flow and coverage logic puzzles.

1. Find both endpoints of each colour on the grid
2. Drag from one endpoint to the other to lay the pipe
3. Route the pipes so that every square ends up covered
4. Redraw a colour when it blocks the space another one needs

• Drag: Draw a pipe between two matching endpoints
• Tap / click: Clear a pipe you want to redraw

Objectives

• Connect every matching pair of endpoints
• Cover the entire board with pipes
• Solve each level without leaving a gap

The run ends or fails when

• Every pair is linked but empty squares remain, so the board stays unsolved

• Endpoint-to-endpoint pipe drawing
• Full-coverage solving requirement
• Grids that grow in size and colour count

• Start with the pair sitting closest to a corner, since its route is most constrained
• Send pipes around the outside first and fill the middle afterwards
• When a colour has an obvious short route, treat that as suspicious and check coverage
