My previous article, "Low Stakes Live Games Differ From Online," pointed out that live, low-stakes no-limit hold'em games — what I call "Donkey Games" — play much differently than much tougher online games.
One key statistic showing that difference is VPIP percentage, which refers to how often players Voluntarily Put money In the Pot. This is simply a measure of how loose a player is.
We see from Figure 1 (Row 1) that the average Vegas $1/$2 player has a VPIP of 37 percent, which is nearly 70 percent looser than the average online NL100 player who has a VPIP of just 22 percent.
