Chalk Harbour is for adults of 19 and over. Every coin here is virtual, carries no monetary value, and cannot be bought, sold, cashed out or swapped for anything. There is nothing on the site to buy, no prize worth anything in the real world, and a good run here tells you nothing about real-money gambling.
