Carbon Poker is offering a March Madness themed reload of their own. This bonus is 75% up to $500, and requires 100 points per $1. That makes it one of their slower clearing reloads of recent months. But, they give you 4 months to clear it, which is nice. Use the code MADNESS before April 1st to take advantage of this bonus. This is a great time to play on Carbon as they are also running a March Madness promotion where you can earn cash prizes, on top of 30% rakeback. Not a member of Carbon Poker?
