메라의 플로우 링크 guide
A link puzzle: join each pair of dots that share a colour and number with a pipe, and fill every square of the board. Pipes may not overlap, and the board is not finished while even one square is left bare. Every board has exactly one solution, and any pipe can be redrawn at any time, so no move is ever final.

How to play
- Choose an unlocked size from 5×5 (5 colours), 6×6 (7 colours) and 7×7 (10 colours). Only 5×5 is open at first; solving a size unlocks the next.
- Drag from a dot with your finger or mouse to draw a pipe up, down, left or right. When it reaches the matching dot the colour is joined and the pipe stops there.
- Moving back over the squares you just drew rubs the pipe out. Grab an existing pipe anywhere along its length to redraw it from that point.
- Drawing over another colour's pipe cuts that pipe short where they meet. You cannot enter a square holding another colour's dot.
- On a keyboard, move the cursor with the arrow keys, press Enter to grab a pipe, then draw with the arrows. H gives a hint, X clears the current colour and R restarts; a gamepad does the same with the D-pad and A.
- The board is complete when every colour is joined and no squares remain empty. Score is 400 plus 40 × the board's side length, plus 90 for each unused hint.
Strategy tips
- Start with dots in corners and against walls. Pipes that hug the edge have few possible directions, so their route is nearly fixed.
- If you leave an empty square that no pipe can still reach, the board cannot be finished. After each pipe, check that nearby empty squares still touch other empty squares or an open pipe end.
- Joining pairs whose dots sit close together first tidies up the remaining space and makes it easier for far-apart colours to loop around and fill it.
- Each board has three hints, and each one lays a colour that does not yet match the answer along its correct route. No hints earns three stars, one hint two, and two or more one.
- R (restart) clears the pipes on the same board but keeps the number of hints already used. Use Start or the stage picker for a fresh board.
Common questions
I joined every dot but the board did not finish.
The board is only complete when every square is covered by a pipe. Bend a longer pipe through the empty squares until the remaining-square count reaches zero.
What happens to my pipes when I use a hint?
The hinted colour is laid along its correct route, and any other pipe that crossed it is cut short just before the first shared square, as if you had drawn over it yourself. Reconnect the cut colours around the hinted route.
Is the board the same every time?
Each start or stage choice deals a new board, and every board has exactly one answer. A board in progress is saved when you pause or leave the tab, so you can pick it up again later.
