A game server is configured to implement a multiplayer online computer-implemented game that provides an inflationary economy system which allows for growth in a player's in-game virtual currency with an increase in game level or experience, while attenuating the in-game purchasing power by concomitantly inflating virtual currency value of predefined inflationary features. The inflationary features include rewards or winnings available by the player pursuant to gameplay success. Players at different inflationary levels can compete in-game for a common reward or jackpot, but a virtual currency value of the reward is denominated differently at different inflation levels.
