7×7 Pipe Puzzles
A 7×7 board is the normal puzzle length. Forty-nine cells and 5 or 6 colors. A pair is no longer obvious from a glance, and a sitting is still short enough to finish without clearing the desk.
This is the size the tubes page uses when it talks about the pipe skin. Square ends and a thicker line help once several paths run side by side. The rules are unchanged from 5×5.
All 100 levels are listed below. Next, after the last one, opens the 10×10 pack.

7×7 puzzle rules
- Connect each pair of same-colored dots with a line.
- The level is clear once every pair is connected. Empty cells can stay empty.
- Lines cannot cross.
This pack is 49 cells and 5 or 6 colors. The clear is the same as on every other size: every pair joined by one line. Cells left over can stay empty.
Lines still cannot share a cell. A larger grid does not add diagonals, timers that fail you, or tiles to rotate.
How to play a 7×7 board
- Start with any pair whose ends are already close.
- Keep a path off the only exit of a corner endpoint.
- Retract or undo as soon as a line sits on another color's corridor.
- Stop when every pair is connected. Do not keep drawing to cover blank cells.
Pick a level from the full list below. The link text is the level name, such as 7x7 puzzle #1, and the address stays on this page. Stars on the card are that level's difficulty inside the 7×7 pack.
7×7 questions
- How many 7×7 levels are there?
- One hundred. Every level in the pack is linked on this page. Other sizes are separate packs with their own 100 levels.
- How many colors does a 7×7 puzzle use?
- Boards in this pack use 5 or 6 colors. The color count is why this size feels different. The pairing rule does not change.
- Do I have to fill every cell?
- No. The level is clear when every pair is connected. Empty cells can stay empty on this size and on the others.
