A method includes operating a bingo player station in a first play mode in which the result for a respective bingo game play initiated through the bingo player station is assigned according to a first pattern list. In response to detecting a trigger event, the bingo player station is switched from the first play mode to a second play mode and then the bingo player station is operated in this second play mode. In the second play mode, the result for a respective bingo game play initiated through the bingo player station is assigned according to a second pattern list. The bingo player station is switched from the second play mode to the first play mode in response to a return event. Both the first pattern list and the second pattern list may share at least one result level and at least one common result indicator. However, the two pattern lists are different so that a given bingo pattern correlated to a prize in one of the pattern maps may correlate to a different prize or no prize in the other pattern map.
