Yes, gambling is indeed a form of mental sport because it not only depends on physical attributes, but it also involves using one's thinking faculty to do some calculations and draw up strategies to make sure they win games and other sports that they deem fit to get involved with. However, gambling is not the only form of mental sport; others, such as games we play online and with people, also help to build our thinking faculty. Have you ever asked yourself why kids who play games a lot are very sharp and smart? That is one of the attributes of playing games, the more they play, the more they put their brain into exercise and it keeps them thinking very fast on the next move to make so that they will be on the safe side which they also apply in other activities they get themselves involved in.
