Star Coins cannot be obtained in-game; they can only be bought from the game's official website. Star Riders receive 100 Star Coins every Saturday until the player's subscription runs out. The only ways of obtaining Star Coins for free are the 100 Coins given upon account creation and sometimes through Redeem Codes.
"STARS600" is the most popular first-deposit PokerStars bonus code. PokerStars will contact you with any new promo codes, while PokerNews' PokerStars pages are kept up-to-date with the latest offers and promotions.
