Catch the heart balloon to the mysterious Love Island to trade in your Love Charms for $Flower or shop rewards. Don’t forget to solve the Flower Puzzle to win a bronze love box once a day!
When it’s time, go to Plaza and click the notification at bottom-left, or walk up to the balloon and click to get whisked away to Love Island!

(Clicking this notification will teleport you to Love Island!)
Work with other players to solve the flower puzzle and win a bronze love box once a day! The goal is to get all petals to turn Orange.
Dull color = Not enough players on the petal
Orange = Perfect amount of players on the petal
Red = Too many players on the petal
Don't worry if it takes a while to solve it. The point is to get players to work together, which can sometimes take a while. Players may be brand new and not know what to do, or experience lag or connection loss that makes it seem like they're standing on that red petal for no reason. If you can't get the reward, don't fret, as it is relatively small and you'll get another chance later.
Are there players idling on one petal forcing it to be stuck on red? Try changing servers and try your luck elsewhere. Go to Settings -> Plaza Settings -> Change Server

VIP players can go to the well and exchange your hard-earned Love Charms for Flower at a rate of 50 Love Charms = 1 Flower! There is a daily limit of 10,000 Love Charms (200 Flower)

Save up and spend those love charms on some neat items! Boosts like the hour glass, decor like the statue and rugs, cosmetic wearables like the dino onesie and love aura. Shop items change out daily so check back often!
You can use sfl.world to check that day’s rewards, just enter your farm id and see the Checklist section on your Info Page.

In-game you can check two ways: Going directly to the Balloon itself, or your Codex. The Balloon flies three times a day for 30 minutes, and the displayed times are conveniently in your time zone.
