Freerolls
A Online poker Game tournament which has no entry fee is called a Freeroll.
Typically the prize in poker tournaments would include the total of the entry fees less the fee for the house. However, a freeroll prize pool is derived from a donation from the house, broadcast right fees, admission and sponsorship fees or a combination of these.
Depending on the popularity of the casino, whether traditional or online as well as the frequency of players will determine the allowance of freeroll tournaments to its players. Many of the freerolls consist of invitation-only tournaments.
In order to restrict registration, freerolls maty also be protected by freeroll passwords.
It is not unusual to pay to play in a freeroll feeder tournament allowing you a free entry to another tournament; however, having already paid once to go on the next level, it is debatable whether these second level tournaments can be called 'freerolls'. This format is typical of poker freeroll tournaments both on the Internet and in the 'bricks and mortar' sites.
