Sea Strike is a classic guessing-and-deduction duel at sea. Arrange your five ships on a 10 × 10 grid, then take turns calling squares on the enemy sea. Each shot is a miss, a hit, or — when you hit a ship’s last square — a sinking. Use the pattern of hits to hunt down every enemy ship before the computer finds yours. Three computer levels range from random shooting to a sharp probability hunter.

How to play Sea Strike

Rules

  • Arrange your fleet of five ships (lengths 5, 4, 3, 3 and 2), straight across or down, without overlapping.
  • Take turns firing at one square of the enemy sea. A white dot is a miss, a glowing marker a hit.
  • When every square of a ship is hit, it sinks and is revealed.
  • Sink the whole enemy fleet to win. The side that fires first alternates between games.
  • Fewer shots means a higher score, multiplied by the computer level.

Tips and strategy

  • Hunt on a checkerboard pattern: every ship covers at least one square of each colour.
  • After a hit, try the four neighbouring squares; after two hits, keep going along the line.
  • Late in the game, look for gaps big enough to hold the ships still afloat.
  • Spread your own ships out so one lucky area does not reveal several.
