Question one: Could you please settle a small wager. On any Megabucks jackpot, I contend that the slot manufacturer is responsible for paying when a jackpot is hit. My friend is equally sure that it's the casinos responsibility. Who wins? Question two: Whenever I read about Megabucks being hit, the winner almost always opts for the lump-sum payout. But how much the winner receives is never revealed. Why not? And do you know how much someone might wind up with?

With the introduction of the new $5 bill, I take it that all the bill changers and bill readers need to be changed to accept the new money? How long does it take to change out each bill changer and what is the cost of doing this?

Is there a website that states the current numbers and kinds of slot machines and video poker games (as well as the available denominations of them) that each casino offers?

Which casinos in Las Vegas (the Strip and downtown) still accept coins?

I know that a lot of casinos are affiliated with each other. Just how many "players cards" would I need to play everywhere in Las Vegas?

Which casinos, if any, track card play (blackjack) electronically for comp ratings?

I read your Question of the Day from 12/21/07 about playing in video poker tournaments. While nothing in that QoD was incorrect, there's a lot more that can be said. May I?

After 15 years of gambling, I experienced something new and possibly illegal. I was playing roulette with $25 inside chips. The size of the ball was changed a couple of times. I have seen ball changes, but never different sizes. The dealer even mentioned he was changing from a "boulder" to a "pebble." Is this legal?

Is there a service or a way to redeem the slot tickets/vouchers once you have returned home? I just found a ticket for $25 in my wallet and do not know anyone going to Vegas in the next 30 days before it expires.

With the passage of four California Indian tribal compacts to increase the number of slot machines at their casinos, it raises the question: What impact have Indian casinos had on Vegas gaming? What do you expect will happen with the slot machine increase? Do you foresee hotel-rate decreases, increased comps, or more generous paytables to attract the California crowd?
