How do I win in the millions – DoubleDown™ Casino Vegas Slots Review

I love this site and I play DAVINCI DIAMONDS all the time. I see the display of high jackpots and I wonder how did that achieve Them. I play all the time and when I get lucky and win 4 or 5 million I bet 200,000 but it won’t hit anything big are good hits long enough Just wondering ?
