Standard Battleship — one shot per turn, five fixed ships, 10×10 grid — is a great game. But after dozens of rounds, you might crave something new. Variants range from time-tested alternatives with dedicated rulesets to casual house rules you can invent on the fly. Here’s a comprehensive tour.

Salvo

Salvo is the oldest known Battleship variant and was actually the first commercially published version.

How It Works

  • Each turn, you fire one shot per surviving ship. At the start, that’s five shots per turn.
  • After calling all your coordinates, the defender checks each one and announces the total number of hits and misses — but does not reveal which specific shots hit.
  • As your ships are sunk, you fire fewer shots per turn.

Strategic Impact

Salvo rewards deductive reasoning. When you fire five shots and are told “two hits,” you need to figure out which two of your five shots connected. Experienced Salvo players carefully choose shot arrangements that make deduction easier — for example, spacing shots so that each possible combination of two hits implies different ship locations.

Turn Your surviving ships Shots fired
1 5 5
5 4 (Destroyer sunk) 4
12 3 3

Commanders Battleship

Released by Hasbro, Commanders Battleship adds a deck of special-ability cards to the standard game.

Common Abilities

Card Effect
Radar Scan Reveals whether any ship occupies a 3×3 area
Air Strike Hits all squares in a single row or column section
Shield Blocks the next hit on one of your ships
Recon Plane Reveals the exact location of one enemy Destroyer
Extra Shot Fire two shots this turn instead of one

Strategic Impact

Card management becomes a major strategic dimension. Do you use your Radar Scan early to find a ship or save it for the endgame when the last ship is hiding among confirmed misses? Timing abilities correctly separates average players from top Commanders players.

Team Battleship

Setup

  • Two teams of two (or more) players each.
  • Each team shares one ocean grid but places ships collaboratively.
  • On each turn, teammates discuss and agree on a shot (or one player calls shots while the other manages tracking).

Strategic Impact

Communication and collaboration add a social dimension. Teams can split the board — one player “owns” the left half, one owns the right — or delegate roles (one does hunt-mode analysis, the other handles target-mode follow-up). Team Battleship is excellent for parties and game nights.

Free-for-All (3+ Players)

Setup

  • Each player has their own ocean grid.
  • On your turn, you choose which opponent to fire at and call a coordinate on their grid.
  • The target opponent announces hit or miss.

Strategic Impact

Diplomacy and threat evaluation matter. Do you focus fire on the leading player or spread damage? Players who are being targeted may band together informally against the aggressor. It introduces negotiation dynamics absent from two-player games.

Hidden Fleet Movement

In this variant, ships are not stationary.

Rules

  • After each of your turns, you may move one ship by sliding it one square in any direction (forward, back, left, or right), as long as it remains fully on the grid and does not overlap another ship.
  • A ship that has been partially hit can still be moved.

Strategic Impact

Movement dramatically changes the game. Hits become less decisive because a partially damaged ship can slide away, forcing you to relocate it. Players must balance offensive shot selection with defensive repositioning. Games tend to last longer and require more adaptive thinking.

Expanded Grid

Rules

  • Use a 12×12, 15×15, or even 20×20 grid instead of the standard 10×10.
  • Add additional ships to fill the larger space — a second Cruiser, a Patrol Boat (1 square), or custom ships.

Strategic Impact

Larger grids make the hunt phase considerably longer and amplify the importance of efficient search patterns. Parity and probability strategies become even more critical because the ratio of ship squares to total squares decreases.

Grid size Total squares Default fleet squares Ship coverage
10×10 100 17 17%
12×12 144 17 12%
15×15 225 17 8%

Speed Battleship

Rules

  • Both players fire simultaneously instead of alternating turns.
  • A timer (30 seconds or 1 minute) runs continuously.
  • When the timer buzzes, both players call their shot at the same time, and results are resolved simultaneously.

Strategic Impact

Speed Battleship tests quick decision-making and eliminates the downtime of waiting for your opponent’s turn. It works especially well in digital implementations where simultaneous resolution is handled automatically.

Beyond formal variants, many players use custom rules to keep the game fresh:

House Rule Description
Bonus shot on sink Sinking a ship earns you an immediate extra shot
Mine placement Each player places 1–3 mines; hitting one costs you a turn
Fog zones Certain grid areas are “foggy” — hits there aren’t confirmed for two turns
Progressive shots Start with 1 shot per turn, gain an additional shot every 5 turns
Ship repair Once per game, remove one hit peg from one of your ships

Choosing the Right Variant

No matter which variant you choose, the core appeal of Battleship remains — hidden information, logical deduction, and the thrill of sinking your opponent’s fleet. Try one variant at a time and find the twist that keeps you coming back.
