The objective of the game is to obtain coins by shooting fish or objects. In order to start shooting, a player should choose an object and tap or click on it. When a cannon is fired into empty space and reaches the game window border, it will ricochet. If it doesn’t reach any fish or object at the first bounce, it will ricochet again and keep doing so until it reaches any target.
The Target Lock switches the cannon to a special electric cannon and keeps shooting at the chosen fish automatically. It can be enabled by double-clicking a fish and disabled by clicking any empty area. Once enabled, Target Lock is active until it is disabled manually. When the fish targeted is killed or swims out of the screen, the electric cannon will target at another fish. If there is none, the electric cannon will stop firing until one appears. The cost of electricity is the same as the cost of the bullet. The bet for Target Lock can be changed by clicking on the cannon. Only one fish or object can be target-locked at a time.
The player may choose the Autofire function to shoot fish and objects. In order to activate the Autofire mode, a player should double click on any empty area. When the Autofire mode is on, the cannon keeps shooting automatically at a constant pace at the direction where the mouse cursor is located. Moving the mouse cursor changes the direction of the bullets. To disable the Autofire mode, a player should single click on any empty area.
The Ocean Ruler game has four game modes, each containing its own Boss. It is possible to kill multiple Bosses during each mode with all features available at the same time. Game modes change automatically during the game session.
Fish inside bubbles can trigger the Multiplier feature. Once the fish is killed, its prize will be multiplied by a random multiplier. The multiplier values are x2, x3, x4, and x5. The multipliers keep rotating around the arrow until one of them stops at the arrowhead. The multiplier is randomly chosen and applied to the payout of the blasted fish.
Once a bomb explodes it will kill all the fish on the screen except for dragons, bosses and crabs. If there are no fish on the screen you will get a prize of 5x your bet. Max win - 5000x your bet.
The Rockets feature is randomly triggered after any regular shot. Up to 3 free rockets can be awarded and automatically target random fish on the screen.
Once the player kills the fish inside the vortex, all fish of the same kind on the screen will be sucked into the vortex.
