As you play and win Fringo games, you collect Fringo Points. The winner of each game of Fringo is the player who collected the most Points, but those Points are still important after the game is over.
Fringo Points are what unlock new Fringo islands, which feature new Power-Ups, larger wagers, different Fruits, and different game-play mechanics.
You can see your Fringo Point total on the Fringo main page (where your avatar is displayed) along with how many Points you need to unlock the next island.
Wylde needs 72,550 more Fringo Points to unlock the next island.
