"Pay-to-Win" refers to a gaming model where players can gain significant advantages by spending real money. This often includes purchasing powerful items, upgrades, or characters that enhance gameplay, making it easier to win against others who may not spend money. This model is commonly found in mobile games and online multiplayer games, where players can choose to invest money to improve their chances of success. Critics argue that it creates an uneven playing field, as those who pay can dominate over players who prefer to play for free, leading to frustration and dissatisfaction within the gaming community.
