Battleship — free browser game

Hide a fleet of five ships on a 10×10 sea (Carrier 5, Battleship 4, Cruiser 3, Submarine 3, Destroyer 2 — 17 cells in total) and sink the enemy's matching fleet before they sink yours. Both fleets are placed randomly at the start; you can see your ships in the bottom grid and tap Shuffle to re-roll the layout until the first shot is fired. On your turn, click any cell on the enemy grid: an empty cell shows a blue miss, a hit shows red, and the last hit on a ship marks the cells as sunk with a black outline (the status bar tells you which class went down). Every turn is one shot — hit or miss, the turn passes to the AI, which uses neighbour-scan logic to chase wounded ships. R or New Game starts a fresh round; the scoreboard remembers your wins and losses. Tip: the AI hunts in a checkerboard pattern, so spread your ships rather than hugging a single edge. When you land a hit, work the row and column outward immediately rather than wandering off.
