- Tap a lantern. It flips, and so do the lanterns right above, below, left and right of it: a plus shape. Dark ones light up, lit ones go dark.
- Light all 25 lanterns to solve the puzzle.
- Tapping the same lantern twice cancels itself out, so the order does not matter, only which lanterns you tap. Undo is always there.
Tip: work from the top down. For each dark lantern in a row, tap the lantern directly below it. That lights it without touching the rows above. Repeat row by row. If the bottom row still has dark lanterns at the end, undo back to the start, try a different set of taps in the top row, and work down again.
3 1
“3 1” means a block of 3 filled tiles, a gap, then 1 more.
- Each number is a block of filled tiles in that row, in order from left to right. Blocks always have at least one empty tile between them. Column numbers work the same way, read from top to bottom.
- Tap a tile to fill it. Tap again to put a dot in it, meaning “definitely empty”. Tap a third time to clear it. Dots are just notes for you.
- Make every row and column match its numbers. A line’s numbers fade once it matches. There is exactly one correct picture.
blank filled dot = empty
Tip: start with the big numbers. A 6 fills its whole line. In a line of 6, a 4 must cover the middle two tiles wherever it sits, and “3 2” fits only one way: three filled, a gap, two filled.
- The blue circle is the spring. Water flows out of it through any pipes that join up.
- Tap a tile to turn it a quarter turn clockwise. Pipes joined to the spring fill with blue water; brown ones are still dry.
- It is solved when every pipe is blue and no pipe end points at nothing, including off the edge of the board.
Tip: start with the corners and edges. A pipe there cannot point off the board, so it usually has only one or two ways to sit.
