Sea Battle

Sea Battle brings the classic hide-your-fleet naval strategy game to your study notes. You hide five ships across your own grid of hidden waters, a cartoon rival captain hides theirs, and then the questions start. Every round opens with a question pulled from your own material: answer it right and your three cannonballs fly true, so you get to call three shots on the enemy's grid. Answer wrong and the shots still fire, but they splash harmlessly into open water — you're shown the correct answer, but the round gives away nothing about where the enemy fleet is hiding. The rival fires a counter-volley every round regardless of your answer, so a hot streak of correct answers is the only way to out-race them to the last ship.

Three correct answers in a row trigger a Full Broadside: your next volley jumps from three cannonballs to five, a reward for accuracy with nothing lost for answering slowly, since nothing on screen ever counts down while you're reading a question. Sink one of the enemy's five ships and the game names it, both directions. Beat Captain Pip, an over-eager duckling admiral who cheers for your hits by mistake, and Captain Marlowe unlocks — a theatrical walrus poet who recites dramatic verse whenever you land a hit. Beat Marlowe and Admiral Greybeard, an ancient sea turtle tactician, is the final challenge, hunting in a checkerboard pattern and locking onto your ship's heading once he lands two hits in a line.

Sea Battle also plays as a Friend Duel: create a room, send the code to a friend, and you both place your fleets in private before alternating volleys on the same shared question deck — no AI captain, just each other's accuracy on the line. Fleet placements are never visible to your opponent under any circumstances; only hit, miss, and sunk results ever cross the wire.

A win with at least 80% answer accuracy earns the Gold Anchor medal; any win earns Silver, and even a loss earns Bronze if you sank two or more enemy ships first. Every match ends on a results screen with your answer accuracy, cannonballs on target, and ships sunk, plus a one-click rematch. There is no timer anywhere in Sea Battle — rounds move at your reading pace, and the only clock that matters is how many correct answers it takes to find the enemy's last ship.
