According to Fadawin, progressive slot machines add a percentage of each bet to the Jackpot or bonus.
Three-wheeled slot machines usually have a single progressive jackpot at the highest return, and you have to bet the biggest coin to qualify to play.
For example, if you bet only one or two coins on a vending machine coin, you can’t win the Progressive Coin. Conversely, putting the highest winning combination on the pay line brings a fixed amount of return.
In a video slot, progressive bonuses are usually multi-layered. Typically there is a four level progression, marked mini, minor, major and Major, or bronze, silver, gold and platinum, or something like that.
On some video slots, all players are eligible for cumulative bonuses, regardless of the stakes. In other cases, you have to bet alone to qualify for the Jackpot.
In addition to the bonus points, which are a requirement for regular gamblers, the Olympics usually pay less than other games.
Make sure you bet enough to qualify for these bonuses. If you can’t afford the stakes, choose the next game.
