The Real Satoshi Scratch Card

****No Popups***** 1 In 4 Wins 500 Satoshi
This is the original satoshi scratch card site, lots of other sites have copied what has been done so well
but all the others will give lower win values and every card you scratch will come with a popup, stay with
the original and be lucky.
