Wrong, just click on the exchange button and you will see that the "joker" is exchangeable for 20 lottery tickets.
1 for 1 or 20 for 1 makes no difference to me but the question remains is there any logical reason you would convert jokers into lottery tickets?
On that note I did buy a couple lottery tickets this week ... but not here. I bought a couple to support a local charity. I have a chance at a nice looking Mercedes ... I almost certainly wont win but its for a good cause and someone will get a nice prize ;)
We have a state lottery here that supposedly supports education but you can't buy tickets online; instead you have to wait in line at a convenience store or other retailers like a gas station; I'm sure I would buy tickets if I could buy them online and I remembered to do so. These odds are well publicized and are so low that it is surprising anyone ever wins but eventually someone always does. I'm not one to waste money but it might be fun to throw out $10-$20 a week in hopes walking away with $1,000,000,000 .... tax bill would suck though ;-)
But back to the point; why would someone trade-in Jokers for IS BF lottery tickets even if it were for a 1000:1? Can you win something that you cant just get with a single joker?
