The on-screen meter of the jackpot shows how much the prize is growing in real-time. The longer players play without landing the main jackpot, the larger it grows. Therefore, the jackpot can be huge. Also, when someone bags the main prize it resets to a large set value to ensure you still have a chance of winning a life-changing amount of money. For example, progressive jackpots usually are in excess of one million US dollars.
