About
Sharpen your logic in quiet focus.
One loop. A few shaded cells. That's the whole rule —
and the longer you look at the board, the clearer your mind becomes.
Use the arrow-and-number clues to shade exactly as many cells as each arrow points to, then draw a single closed loop through every remaining cell. Shaded cells never touch side by side, and clue cells are never shaded or crossed by the loop.
