I get great pleasure from watching Ice Hockey. A contact team sport played on ice.
That is fun. is it similar to regular hokey 
Its hockey but on Ice. Players wear skates and use a puck instead of a ball but I would say that ice hockey is more of a contact sport rather than traditional hockey.
I love to watch it on the TV sometimes. Where does the hockey originate from?
I would have to say that it originated from North America, more so Canada.
Can it be played in tropical regions too?
Yes it can if they have an ice rink though its more popular in Canada, central and eastern Europe, Scandinavia, Russia and the United States.
