by giving the fishies an incentive to keep depositing:
Deposit and Win FREE Cash Every Day!
Make a deposit now and you’ll be rewarded with entry to four $1,000 freerolls per day for 31 days - that’s more than $100,000 in free tournament value! Plus, if you are a first-time depositor, use the bonus code ‘STARS600’ and you’re also eligible for the regular 100% welcome bonus up to $600.
Want to keep playing once your ticket has expired? Simply reload your account and you’ll be credited with a new one. You can use the reload code ‘100K’ once a month, which gives you another 31 days of play from the time of your deposit.
The $1,000 freeroll tourneys also use a special freebuy format. This means that entry is free, but you can re-buy as many times as you want for the first hour for just $0.30, boosting the prize pool each time. It’s one of the biggest daily freeroll series PokerStars has ever offered, giving you great value on your deposit.
