At least you went all in- Ultimate 7's is gonna have the highest payout percentage and likely the best odds of the four. And of course largest top prize.
Looking at the design of the 7's fam fam, I am puzzled why they chose this theme. I appreciate the floating bills artwork and do have an attraction to 7 as a number, but what strikes me as odd is that there is no 7-based prize structure (like the TP could be $7,000,000) except for the Second Chance drawing (seven $7k winners). Also, I noticed there is no standard Win All symbol or Win Prize symbol. They could have had something like "Uncover a "7" symbol, automatically win $100" or something.
Only seems to be the bonus multipliers that you typically find on X the Money games.
Anyway, when you say purple Mega Millions ticket, were you referring to Winning Millions ($20), from a couple years back? I hit $250 on that game with a Win All. And the first time I played I got a free ticket, second was a $100 winner.
