A family game with polyominoes where players take the role of Sea Dragons protecting the ocean from daring pirates and collecting treasures. On your turn, you play a Pattern card from your hand to place a Sea Dragon on the board, increasing your presence on the four Sea Realms. But beware! You won’t be able to place your Sea Dragons next to each other and placing them next to your rivals’ Sea Dragons will grant them benefits. Claim victory by winning the majorities on each of the four Sea Realms, completing missions and collecting treasures.
