Your goal

The purpose of the game is to sink as many ships as possible. To sink a ship one has to collect all "Sink ship" letters first. This can be done by shooting the Cannon in single ball play or by shooting the ramps during multiball. After collecting all "Sink ship" letters the Locker will be opened (during multiball you'll have to wait till single ball starts). Shoot the locker to load the cannon. Shoot the Broadside with the cannon to sink a ship. After sinking the second ship special will be lit.

Starting multiball

Start multiball by lighting all 4 LOCK letters and lock the ball in the Pirate's cove. This starts 2-ball multiball. Start 3-ball multiball during 2-ball mutliball by locking both balls again.

Special shots

There are two shots in the game that are very hard to get.
The first one called "Sneak attack" will reward 1 million point. The ball has to go up the left ramp and down the middle ramp instead of the right orbit. Watch out, it will head towards the right outlane.
The second one is called "Three bank ricochet" and worth 3 million points. You will have to hit all three banks of stand up targets in one shot and complete at least one of the banks (here I'm not quite sure) to get it.
