Clearing this site’s data in your browser settings brings the cookie banner back. Nubbin keeps the coins on your account, so log in afterwards and the satchel is full again.
Fern Fossil Valley is open only to adults aged 19 or over. Each reel in the valley turns on virtual coins of no monetary value, coins that can never be bought, sold, withdrawn or exchanged. Nubbin’s satchel hides no coin shop, the fern path passes no payment page, no prize of real-world value is on offer, and success here does not imply future success at real-money gambling.
