Of the $10 tickets its really hard to say. Judging on past wins on the 200 Million Spectacular, there is typically a winner every 5-6 months. The last 2 wins on that game came on:
11/12/2010 (Orlando, FL) & 06/08/10 (Largo, FL)
Even though this game typically produces a winner every 5-6 months on average, anything can happen. I still play this game because I like it.
Like Luis said, its all about luck. But I personally play 200 Million Spectacular & Casino action & 100 Year for life. All 3 of them have a decent amount of Top Prizes remaining, but the Casino action is farthest out and seems to be due a Top Prize anyday now.
But it's so hard to say ya know. Anything can happen
Good luck to you
