Rules:
• Shade some white cells such that no two shaded cells are orthogonally adjacent, and draw a loop that travels orthogonally through all unshaded white cells without intersecting itself or crossing bold borders.
• Clues marked with arrows give the sum of all shaded cells in the given direction, or directions combined, where a cell's value is 1 if it is inside the loop and -1 if it is outside the loop.
• Gears visited by the loop must alternate inside and outside (or vice versa). A gear is considered visited when the loop travels directly from a cell not touching that gear to a cell touching that gear.
