Free Roll.
During my introduction to Online Texas Holdem in 2005 I learned to look for the Free Roll tournaments at the various Holdem websites I visited. Free Roll means no money required to buy-in to the designated tournament. Anyone can enter the tournament to try to win one of the tournament prizes. Different sites set up different values.
Initially, JimFeistPoker.com offered registered players two promo coins per day (no longer offered). Each could be used to gain entry into satellite games toward a weekly $1000 final game.
Ultimate Bet.com has several Free Roll tournaments each day with prizes including Prize Pool points, Bonus Dollars, and Tournament Entry Chips (TEC). A TEC can be used to enter a $100 buy-in real money tournament.
FullTiltPoker.com has at least 2 Free Roll games per day, each playing for $40 real money.
PokerStars.com has Free Roll games into special events such as the World Poker Tour and the European Poker Tour.
Some sites restrict some of the Free Roll tournaments to Frequent Player Point (FPP) redemption or Real Money deposit status.
The down side of this Free Roll world is that even though you are at a table of usually 9 players, there are from 900 to 2500 players in the tournament all going for the Free Roll prize. Thus, for the small reward you get if you win the tournament prize, a large amount of time is spent in front of the computer. Some of the Free Roll tournaments last 4 to 6 hours.
I have only finished in the money once on the Free Roll tournaments I have entered. I will still enter them periodically for a change of pace from the Sit & Go games, but I will stick to the Sit & Go games in the long run.
