About this game

This is a tabletop game called "Naval Battle Game."

Each player deploys a battleship, destroyer, and submarine,
taking turns moving or attacking. The first player to defeat all of their opponents wins.

Your opponent cannot be seen. This is a game where you're given only attack and movement information,
and must guess your opponent's position.

While there are various local rules,
this game's rules are as follows:
- Movement is one square up, down, left, right (east, west, north, south)
- Attack is one square around the target, including diagonals
- For opponent movement, you know the ship's name and direction
- For opponent attacks, you know the number of shots fired
- If your attack hits, you know the extent of the damage
- Heavy Damage ⇒ 1 HP remaining
- Moderate Damage ⇒ 2 HP remaining
- Sunk ⇒ The opponent's ship is sunk
- If your attack misses, you know whether there is an opponent nearby
- Big Waves ⇒ No one within one square diagonally around the attacked square
- High Waves ⇒ There is a ship somewhere within one square diagonally around the attacked square
- There may be multiple ships

Special support weapons are also available so anyone can win.
Watching an ad will unlock them in that stage.
This will disrupt the game balance, so we recommend using them as a last resort.

It’s a tabletop game called “Naval Battle.”

Each player positions battleships, destroyers, and submarines, then alternates between moving or attacking. The player who sinks all of the opponent’s ships first wins. The opponent’s positions are hidden, and you only receive information from their attacks and movements to deduce their location.

Although there are many local rule variations, this game follows these rules:

Movement: 1 square up, down, left, or right (north, south, east, west)

Attack: Any surrounding square within 1, including diagonals

Opponent’s movement: You know the ship’s name and direction

Opponent’s attack: You know the number of shells fired

When an attack hits, you know the degree of damage:

Heavy damage ⇒ Durability remaining: 1

Medium damage ⇒ Durability remaining: 2

Sunk ⇒ The opponent’s ship is destroyed

When an attack misses, you learn whether an opponent is nearby:

“Calm sea” ⇒ No ships in any surrounding square within 1 including diagonals

“High waves” ⇒ At least one ship somewhere in the surrounding square within 1 including diagonals, possibly more than one

To give everyone a chance to win, there are also special support weapons.
They can be unlocked for use in a stage by watching an ad.
Since they disrupt game balance, it’s recommended to use them only as a last resort.
