Pirate Battle is a game mode that allows you to win gold bars by answering questions from any of the game’s categories. You can access this mode in the tab ‘Events’, under the ‘Missions’ section.
Once you are there you will see 6 objectives, which you will have to complete to get the chest.
This mode is similar to the popular game ‘Battleship’. Each user will have a board in which their ships will be randomly placed. The objective is that you bring down your opponent's ships, and complete the objective.
When your turn comes, you will see all the available spots to attack; if you select a spot that has your opponent’s ship, you will be able to answer a question to bring it down. If your answer is wrong, you can use gold bars (if you have the ad-free version) or watch a promotional video to get another chance.
If you bring all your opponent’s ships down, you will complete your objective. The next objective will then become available and so on, until the game is finished.
If you don’t complete the objective or you give up, you can play again by using three tickets (for the ad-free version) or by watching a promotional video.
