Yeah I ran into on some ads before and finally gave in to try it. I at least login to get my free play tickets each day. They do have expirations. Unless you can time it right, typically you can only have 2-3 at a time. Every 10th and 20th of each month they give 2 extra tickets to play. Making for 3 tickets that day (just remember, Japan is ahead in time. So 10th and 20th for a good few of us will be the 9th and 19th).
