Battle rules



The turret icon on the middle of a ship’s card indicates how many sides the dice has and how many of them to be used when attacking. If the attack on the dice roll is higher than or equal to the defence of a targeted ship, it will sink that ship. The defence is the shield icon on the left of the card. The barrel icon on the right is the cost.


A battle is played in loops of battle rounds. Each battle round, ships fire in order of tier (the number indicated in the ship’s picture) until all tiers have fired and the next battle round begins. All ships of the same tier will fire simultaneously and each ship can target independently. For instance battleships (tier 3) will go third, both players will choose their targets and roll at the same time. If the opponent targets your battleship and you target theirs, it is possible for both side’s battleships to be sunk as a result. In other words, you only count the casualties on both sides after both sides have rolled for that tier.


Ships target independently, for example, you may choose for one u-boat to target a carrier and the other a battleship. However, even though a u-boat rolls with 2 dice, both these dice will only count towards a single ship. The only exception is the aircraft carrier which can target different ships with each die. When rolling for destroyers, if there are 2 sixes among the dice rolled, this can be counted as a 10 to destroy targets with more than 6 defence.
U-boats are unique in that they stay submerged until they fire (firing is optional). While they are submerged they have a defence of 10. Although they are the first to fire in a battle round (tier 1), once they have fired they will become unsubmerged with a defence of 5 until all other tier levels have their turn and a new battle round starts.



In battle a fleet is divided into 2 groups: the battle group and the carrier group. Battleships, battle cruisers and heavy cruisers are always in the battle group and cannot form part of the carrier group, likewise carriers cannot form part of the battle group. Destroyers and light cruisers can be placed in either group and in any arrangement that you choose (before the battle starts). You can move those ships between the battle group and carrier group during battle, however, doing so prevents them for firing for that battle round and the ships do not move group until the end of the round. U-boats are not in either group, they can target any ship and be targeted by any ship.

- A battle group can only engage the opponent’s carrier group after their battle group has been destroyed.
- Carriers can target any ship within any group and can only be targeted by u-boats and carriers, unless the battle group has been destroyed in accordance with rule 1.
- Other ships in the carrier group can only defend, i.e. target ships that have targeted the carrier group, except enemy carriers in accordance with the rule 2.
If you have lost your battle group you cannot reform a new battle group from your carrier group.
Shipyard
If a destroyer (tier 5) is present the battle group it will increase the defence of tier 4 & 3 ships by 1.
Each destroyer in a carrier group adds 1 defence to the carriers up to a max of 10.
Destroyers roll a 6 sided dice against u-boats.


If a tier 4 ship is present the battle group it will increase the defence of battleships and battle cruisers by 1.
Each light cruiser in the carrier fleet adds 2 defence to aircraft carriers up to a max of 10.
The light cruiser has a defence of 6 if destroyers are present in the same group.
Light cruisers roll a 6 sided dice against u-boats.
If a tier 4 ship is present the battle group it will increase the defence of battleships and battle cruisers by 1.
The heavy cruiser has a defence of 6 if destroyers are present in the battle group.
Heavy cruisers roll a 6 sided dice against u-boats. They cannot form part of the carrier group.


As a tier 3 ship the battle cruiser gains a defensive bonus from lower tiers in the battle group. This can increase their defence up to 8.
Battle cruisers roll a 6 sided dice against u-boats. They cannot form part of the carrier group.
As a tier 3 ship the battleship gains a defensive bonus from lower tiers in the battle group. This can increase their defence up to 10.
Battleships roll a 6 sided dice against u-boats. They cannot form part of the carrier group.


The light carrier starts with a defence of 5 but this can be boosted up to 10 with destroyer and light cruiser escorts.
Light carriers roll a 10 sided dice against any target.
The aircraft carrier starts with a defence of 6 but this can be boosted up to 10 with destroyer and light cruiser escorts.
Each carrier rolls two 10 sided dice which can target independently.


The u-boat has a defence of 10 while submerged. Firing the u-boat will make it unsubmerged thus reducing it’s defence to 5 for the remainder of the battle round.
The u-boat must rolls two 10 sided dice against the same target.
