I was searching all over the internet and could not find the answer.

Do they need a license ?

The legality issue will depend on which country that the gambling operation will take place. There are lot of issues before a legal Bitcoin gambling operation will be establish like if Bitcoin and gambling operation are legal in a certain country. If all are legal then gambling owners should request operation permit to their government so that they could legally to operate a online casino or any Bitcoin gambling operations that they desire. Some gambling operations are legal some are not so it will be the players call if they will check the legality of the operations before playing.
