If you aim for the full $600 match, you will get it released in $60 increments for every 240 iRPs earned.
That works out to an impressive 50% rakeback rate. For example, if you made a $100 deposit, your $100 bonus would be released in chunks of $10 for every 40 iRPs you earn. To unlock each chunk, you’ll need to earn 4X the amount of each increment in iRPs. Your deposit bonus is released in chunks of 10% of the amount you deposited.
