Video poker game. See Bonus Aces and Faces paytable.

The total amount wagered on a slot, keno or video poker machine. For video poker, the Coin-in is equal to the total number of hands played times the average amount bet per hand. The term originates from the fact that all slots machines were once "coin droppers" and is still in use today though most machines are now TITO.

(According to IRS.gov) In 1988, Congress enacted the Indian Gaming Regulatory Act (IGRA) to:

1. provide a statutory basis for the operation of gaming by Indian tribes to promote tribal economic development, self-sufficiency, and strong tribal governments;
2. provide a statutory basis for the regulation of Indian gaming to ensure tribes are the primary beneficiaries;
3. establish: a) independent federal regulatory authority for Indian gaming, b) federal standards for Indian gaming, and c) the National Indian Gaming Commission (NIGC), to meet congressional concerns regarding Indian gaming and protect such gaming as a means of generating tribal revenue;
4. shield gaming from organized crime and other corrupting influences; and 5. ensure that gaming is conducted fairly and honestly by both the operators and the players.

Since IGRA’s passage in 1988, tribes and states have successfully negotiated hundreds of Tribal-State gaming compacts. Gaming provides significant revenues for many Indian tribes.

Gambling strategy that seeks to maximize the games return. Also know as Max-ER strategy, this is by far the most common gambling strategy. Other strategies might involve reducing risk (minimizing the variance), for example.

A measure of the variability of a data set or random process. The variance describes how far values lie from the mean (the first moment of the distribution), and is used, along with the mean, and higher moments, to characterize a probability distribution. The Variance is defined as the expectation of (X-µ)^2 where X is value and µ is the expected value or mean. While the combination of the variance and the mean fully describe a normal distribution (gaussian) they are not sufficient to describe the strongly non-normal distribution for video poker. Nonetheless, variance is an important factor to consider and understand in many aspects of video poker. For video poker, typical values of the Variance range roughly from 15 (PKM) to 100 (DBDJ) and is in units of the bet squared.
