If your Bumpkin Level is 20 or higher, your Yakkamon Access Code unlocks tonight at 8:00 PM ET. This is the last Sunflower Land wave — after tonight every level tier is open, and the only route left in is a referral code.
Step 1: Find Yakkamon in the Plaza
Head to the Plaza in Sunflower Land and look for the "Yakkamon" sign next to Stella. Click on it to open the access code panel.
The Yakkamon booth sits right next to Stella in the Plaza.
From there, click "Get Access Code" to receive your unique code.
Step 2: Sign up with your code
Once you have your code, go to yakkamon.com and enter it on the "Enter Trainer Code" screen, then hit Confirm.
Enter your code exactly as shown, then confirm to complete pre-registration.
What tonight actually gets you
Your Monster Egg tier, and nothing else. Eggs go out in sign-up order: the first 10,000 trainers get Platinum, then Gold, Silver, Bronze and Basic as the numbers climb.
Below Level 20, or not on Sunflower Land at all?
You're next, and you don't need a Sunflower Land account. Referral codes open on Aug 4 at 8:00 PM ET — from that moment anyone can register using a code from a trainer who has already signed up.
It's a big moment for the game: the 295,063 Sunflower Land players below Level 20 — around 84% of the entire playerbase — all become eligible at once, alongside everyone outside Sunflower Land.
Full tier breakdown is on the Pre-registration page, the step-by-step lives in the FAQ, and if you get stuck you can ask in our Telegram chat — send the bot your Bumpkin Level and it'll tell you your unlock time.
