Trust me, if you don`t wish to risk your own money go to facebook and play poker there, you have seat out tournaments and you can try to sharp your skills there. In case you are willing to risk a bit of your money then you can go to betcoin.ag and play some micro buy in tournament, you have couple free tournaments also.
Nobody can teach you how to play poker, you need to play and play and learn trough playing. That is the best way if you ask me, I advise you to read about rules if you dont know nothing about poker, then try facebook, then free tournaments, then micro. When you finish that try your tickets, as I know that tickets dont have time limitation.
