Fleet: Battleship Solitaire

Fleet: Battleship Solitaire is a single-player logic puzzle game inspired by the pen-and-paper classic Bimaru (also known as Yubotu or Battleships). Place every ship in the hidden fleet using only the number clues on each row and column — no guessing required. How the puzzles work Each board gives you a grid, a fleet of ships, and a number clue beside every row and column. The clue tells you exactly how many cells in that line contain a ship. Combine the clues with the rule that ships never touch — not even diagonally — and the solution falls into place through pure deduction. What's inside • Four difficulty tiers: Easy 6×6, Medium 8×8, Hard 10×10, and Expert 10×10 with the full naval fleet. • Live validator that highlights row, column, fleet, and adjacency conflicts the moment they appear. • Tri-state cells — tap to mark water, tap again to mark ship, long-press to flood a row or column. • Drag-fill — sweep across cells in one gesture to mark whole lines at once. • Undo and Redo with a 128-move history. • Move counter and elapsed timer per puzzle. • Auto-save — close the app any time and resume right where you left off. • Light and dark themes that follow your system setting. Built for everyone • Full screen reader support. Every cell is labelled for TalkBack with row, column, and state. • Keyboard navigation: arrow keys to move, Space to cycle, Ctrl+Z and Ctrl+Y for undo and redo. • Reduce-motion option that respects accessibility settings. • Plays offline — no internet connection required. If you enjoy Sudoku, Nonogram (Picross), Minesweeper, or other logic and deduction puzzles, Battleship Solitaire is a natural next step. Each puzzle has a unique solution that can always be reached through reasoning alone. Privacy Your progress is stored on your device. Anonymous analytics and crash reports help us improve the app.
