Sea Battle Duo

Sea Battle Duo is the classic naval duel rebuilt for modern screens. Play solo against the AI Admiral, challenge a friend locally, or enjoy the full tabletop experience on iPhone Duo. On every supported iPhone and iPad, your fleet stays hidden until the shell lands. MADE EXTRA SPECIAL BY IPHONE DUO On iPhone Duo, two halves become two private boards. The lower half is your firing map, with live hit markers, sunk-ship reveals and a streak counter that rewards precise aim. The upper half holds your own fleet on a separate board. Fold the device to roughly 90° and stand it on the table: the raised half faces you while its back faces your opponent, turning the device's geometry into a natural shield. No mirrors, angle tricks or peeking over shoulders. A privacy badge confirms tabletop mode, so you always know what your opponent can see. On any other iPhone or iPad, both boards appear in a clean game layout with the same classic rules and full gameplay. TWO WAYS TO PLAY • Vs Computer — battle the AI Admiral, who hunts in patterns, presses its advantage after a hit and never gives you a free turn. Perfect for learning the map, sharpening your streak or playing offline. • Vs Player — face a friend on two nearby devices. One player hosts, the other joins, and local discovery connects them in seconds. Every shot travels peer-to-peer: send a coordinate, receive a hit, miss or sinking result, and update your map. Your fleet never leaves your device. LOCAL BY DESIGN, OFFLINE BY DEFAULT Multiplayer uses Wi‑Fi and Bluetooth nearby — no internet, accounts, matchmaking queues or cloud servers. Lose the signal or move out of range and the match ends cleanly. Solo mode needs no connectivity at all. CLASSIC RULES, MODERN FEEL Ten ships, twelve-by-nine waters, and the rule every veteran knows: hit and fire again; miss and the turn passes. When a ship sinks, its outline appears with a halo of confirmed misses, keeping deduction fair. Live stats track time, accuracy, enemy hulls and your streak. When the battle ends, share a result card with your victory or defeat and all your stats. PRIVATE BY PRINCIPLE No ads. No in-app purchases. No sign-up, tracking or analytics harvesting. The only permission requested is local-network access, used solely to discover a nearby opponent. Nothing about you is collected, stored or transmitted.
