How to earn pearls in Hungry Shark World

In this video i will show you what is the most efficient way to earn pearls in Hungry Shark World (in my opinion)
you can choose two map to earn pearls
Pacific Wasteland and Arctic Apocalypse
Pacific Wasteland is the easier map, you can earn more pearls on Arctic Apocalypse but its pretty hard and i always dies at the end and i must pay gems or watch ad to survive the extinction.
in Pacific Wasteland you will earn at least 100 gems and on Arctic Apocalypse at least 140
i will add another video where i play on the Arctic map
