Starry Night

Starry Night (also known as “Niapuresu”, “Near Place”) is a logic puzzle invented by Naoki Inaba (Japan). The aim is to place one white circle (“sun”), one black circle (“moon”) and one star in every row and column of the grid. Same figures may not touch each other diagonally. The figures outside the grid indicate the distance between the star and circles in that row or column:

• The white circle indicates that the sun is closer to the star than the moon.
• The black circle indicates that the moon is closer to the star than the sun.
• The star outside the grid indicates that the circles are at equal distance from the star in that row or column.
