Abstract

In accordance with one or more embodiments, a first set of results obtained over a plurality of game plays of a game is evaluated to determine whether the results of the first set of results satisfy one or more predetermined criteria. An example of a predetermined criterion is a desired standard deviation. The results may satisfy the desired standard deviation, for example, if a calculated standard deviation of the results is within a predetermined range of the desired standard deviation. In one or more embodiments, if the results do not satisfy the one or more predetermined criteria, the game is adjusted. The game may be adjusted by, for example, adjusting one or more parameters of the game. In accordance with one or more embodiments, a goal of the adjustment may be to adjust the game such that a second set of results, obtained under the game as defined by the adjusted game parameters, are expected to satisfy the one or more predetermined criteria.
