I think Grand maximization refers to the economic concept of maximizing profits or gains to the highest possible level. In the context of gambling, grand maximization can affect the way that gambling affairs are conducted.For gambling operators, grand maximization may lead to changes in the odds or rules of the games to increase their profits, which can negatively impact the players. This may also lead to the offering of high stakes games or incentives to encourage players to bet more, which can increase the risk of problem gambling for vulnerable individuals.
