Scratchers suck... it's like playing slot machines in a casino... you may win a couple bucks here and there, but you never win the jackpot.
Best to forget about the Powerball and Mega Millions games. Someone could play the Powerball (odds 1:175,000,000) or Mega Millions (1:270,000,000) everyday for the next 5000 years and never win. Cash 5 games have much better odds. I only play them when they roll up to $1,000,000, which is rare.
