What is your favorite / preferable kind of lottery:
1. Active or passive approach:
Active: you need to guess winning numbers your self (like 6/45 etc.)
Passive: just buy ticket and wait if the ticket is lucky or not
2. Odds or prize amount?
Will you choose a lottery game with higher odds but lower prize, or lower odds but huge jackpot?
3. Reasonable ticket price?
Thank you everyone who joins the discussion.
Save for stuff like Keno, all the lottery options in my country are active and cost the same. I personally prefer playing 6/42 because of the fewer possible combinations. Sure the prize is lower but in the very rare instance that I do win, there's a far smaller chance that I'll have to share it with anyone, which is what usually happens when stuff like 6/55 reach record high jackpots.
