Game progressives increment the progressive meters on one or several wagers by a certain percentage of the write of the game as a whole.

As such, they share the feature of the time progressive that the progressive meter may increase regardless of the volume played.

Game progressives are well suited for manual games, as it is not NECESSARY to count each progressive wager. The house percentage of game progressive keno games is traditionally calculated by calculating the house percentage of the game as a whole, calculating each progressive wager at its reset value as if it were a straight wager, and then deducting the meter increment from this figure.

For instance, if a game progressive keno game puts 2% of its write to the meter, and the house percentage is calculated at 28.5% ignoring progressive increments, by deducting 2% from 28.5% results in a theoretical house percentage of 26.5%.

It is not unusual for a game progressive meter to "go negative" in house percentage from the player’s point of view, particularly when the dollar volume going to the meter is high, or the dollar volume played on the progressive wager is low, or both.

For instance, if a progressive \$3 8-spot has an initial reset house percentage of 27%, then the player’s expectation is 73% of \$3, or \$2.19.

If the house is putting 3% of the write to the meter, then the player’s \$3 wager increments the meter by 9Â¡, and the player’s expectation rises to \$2.28.

If the progressive wager amounts to 10% of the dollar volume of the game as a whole, then for every \$3 wagered the progressive, \$27 is wagered on non-progressives, and 81Â¡ is added to the meter.

Thus the player’s expectation rises to \$3.09! In fact, if anything more than 72 cents is added to the meter for every \$3 progressive wager, then the player’s expectation is positive.

In this case, if the dollar volume of the progressive wager is 11.1% or less, then the player’s expectation will be positive in the long run.

This figure may be readily determined by dividing 72Â¡ by .03, which is \$24. \$3 + \$24 = \$27, and 3/27 = 11.1%, which is the break even percentage for progressive players.

If the initial house percentage on the 8-spot is raised to 30%, then the break even volume percentage for the player is lowered to 10%.

If the initial house percentage on the 8-spot is raised to 40%, then the break even volume percentage for the player is lowered to 7.5%.
