Tents Island, also known as “Airando, is a logic puzzle invented by Naoki Inaba (Japan). It consists of a grid with numbers in some cells. The aim is to blacken some cells of a grid according to the rules below:

  • The white cells form a single island.
  • Each numbered cell must be a part of this island.
  • The numbers indicate how many unnumbered white cells can be reached from that cell by moving horizontally or vertically. Numbered cells block access.
