US Patent 8690659 Casino game with next round multipliers

A player plays a first round of a casino slot machine game. If the player achieves a winning outcome on the first round of play, the payouts for the next round of play of the casino game will be increased. The amount of the increase is based on the category of the winning outcome on the first round of play. Each subsequent round of play continues to have increased payouts if the player continues to achieve winning outcomes. When the player has a losing outcome, the payouts revert to the base level. An extra wager may be required from the player to activate this feature during the play of the casino game.
