Oceanar.io is such a fantastic and engaging Agario Style free for all game online in the .io games series. You spawn in the arena as just a small snake roaming through a huge ocean to absorb anything that is smaller than you while staying away from the bigger guys. At first, you are just a single angler fish, but through over time eating, you will assemble a strong fish army that will help you kill the opponents easily. You should prey on the armies that are weaker than you, kill them all to increase your army size and gradually, you will build your highest dominance in the arena. The one who has the bigger group of fish will beat others easily, so keep this rule in mind during the fight and make sure you protect yourself for a chance of surviving. Are you up for this? Come to play it now! Good luck!
Use the mouse to move your fish, click left mouse to attack and use the right mouse to combine smaller fish into bigger ones.
