About Printable Aquarium Puzzles

Aquarium is a water-filling logic puzzle where you determine which cells should be filled with water. The numbers along the edges indicate how many cells in each row or column must contain water. Water behaves realistically - it fills from the bottom and maintains the same level within each aquarium (tank).

How to Solve Aquarium Puzzles

  • Row/Column Clues: Numbers show how many cells must be filled in that line.
  • Water Physics: Water fills from the bottom up in each tank.
  • Connected Tanks: Water level is the same across connected cells in a tank.
  • Use Elimination: Mark cells that must be empty or filled based on constraints.
