Gambling - help, turn into something else

Hello, my friend has Aspergers. He started gambling quite a long time ago, however this has gone out of control lately, because he has been borrowing too much money. I was just wondering if someone would have any ideas I could recommend for him to try, instead of gambling. I was wondering if would it be possible to shift the things he likes in gambling into another activity.

He likes that he is completely focused on one thing, the adrenalin rush, the understandong of the features of different websites and the details of the game.

Does someone have any ideas that might be benefitial for him?

thank you
