Traditional (or "brick and mortar", B&M, live, land-based) venues for playing poker, such as casinos and poker rooms, may be intimidating for novice players and are often located in geographically disparate locations. Also, brick and mortar casinos are reluctant to promote poker because it is difficult for them to profit from it. Though the rake, or time charge, of traditional casinos is often high, the opportunity costs of running a poker room are even higher. Brick and mortar casinos often make much more money by removing poker rooms and adding more slot machines. For example, figures from the Gaming Accounting Firm Joseph Eve estimate that poker accounts for 1% of brick and mortar casino revenues.
