An overlay from what I understand it to be is what a casino has to put out of their pocket to cover a guaranteed prize pool when there isn't enough players to cover the guaranteed amount.
In your example of $250 you would have to figure out how much of your buyin goes to the prize pool and how much goes to the rake, its usually x+y.
So I'm going to guess your 27 cent example is broken into 25+2 cents? 2 is the rake and the casino takes that while the first number goes to the prize pool. You don't count the rake just the initial buyin for the prize pool.
$250/.25 each person puts in the prize pool equals a combination of 1000 buyins and rebuyins (assuming the rebuyin is 25 cents).
So again, the overlay is whatever the casino has to add to a guaranteed prize pool if they don't get enough entrants and rebuys. So lets say they get $225 and the guarantee is for $250 then the overlay is $25.
I never look at this stuff, the only thing that matters to me and I've never been a tourn player is the payout ratio and the number of spots available to cash and whether it moves with the number of entrants or is it set in stone like some satellite tourn where there's only a few seats like the top 3 make the money or is each prize is set in stone like for every TEN $100 entrants will guarantee One $1000 prize.
Are there any way to get heads up on juicy overlays?[/quote]
A lot of
casinos will cancel a tourn if there isn't enough entrants in a tourn to prevent this from happening. And you need 2 to tango in a heads up match so there isn't an overlay in HU SNGs that I know of.
And even for multi entrant tourns the casino will not continue that tourn unless its a promotional tourn like a low buyin tourn to get folks interested in playing but they'll make it up down the line through other mean so they don't mind taking the overlay loss.
