Bimaru

Bimaru is a naval logic puzzle where your mission is simple: locate every ship hiding in the grid.

Each puzzle gives you a fleet to place — submarines, destroyers, cruisers, and battleships — along with numbered clues on every row and column telling you exactly how many ship cells are there. No guessing. Pure deduction.

How to play
• Use the row and column numbers to figure out where each ship must go
• Ships can only be horizontal or vertical
• Ships never touch each other, not even at the corners
• Fill in water cells to eliminate possibilities and zero in on the solution

Features
• Three difficulty levels — Easy (6×6), Medium (8×8), and Hard (10×10)
• Casual mode checks your progress as you play
• Challenge mode lets you work freely and submit when you're confident
• Pre-placed hint cells to get you started
• Need a nudge? Watch a short ad to reveal an extra ship cell
• Track your wins and best times per difficulty

Clean, distraction-free design. No timers unless you want them. Just you and the grid.

If you enjoy Nonograms, Sudoku, or Picross, Bimaru will feel right at home.
