Abstract: When symbols to be stopped on at least one inactivated line other than an activated line of pay lines make a winning combination, whether the winning combination on the inactivated line is to be reflected in a game result or not is determined by lottery. If it is determined that the winning combination on the inactivated line is to be reflected in a game result, a player is awarded in accordance with the winning combination on the inactivated line.

Abstract: A decomposition processing method for ethylene oxide is provided for when concentration of the ethylene oxide to be decomposed in a gas varies. The method comprises steps of reducing the concentration of ethylene oxide in the gas to a predetermined concentration which is less than the highest concentration of the ethylene oxide in the range of the variation, adsorbing ethylene oxide to a photocatalyst which has ethylene oxide adsorbing ability, and decomposing ethylene oxide by action of one of the photocatalyst and a combination of the photocatalyst and plasma. The adsorbing step and decomposing step are conducted after the reducing step.
