HiddenFleet is a free browser-based tactical naval combat game built on the classic 10x10 Sea Battle (battleship-style) rules. We combine the familiar tabletop grid with intelligent, fast AI opponents, real-time multiplayer duels, and a unique territorial Global Campaign mode.
HiddenFleet is a modern reimagining of the classic naval board game. Our mission is to deliver a clean, responsive, and strategic Sea Battle experience where victory is decided by probability calculation, grid reading, and smart tactics rather than sheer luck. Play instantly in your browser with no download required.
We designed the game from the ground up to ensure seamless, fluid gameplay across all devices - from widescreen desktop monitors to mobile phones and tablets. Smooth animations, one-click fleet auto-placement, and an uncluttered dark tactical interface keep you focused on the action.
HiddenFleet offers modes for every playstyle: fast single-player battles against 3 difficulty tiers of responsive AI, instant multiplayer duels with friends via private link or random matchmaking, and our strategic Global Campaign mode across a 6x6 territorial map.
