What Are Progressive Slots?

Progressive slots reserve a portion of each bet to feed a growing jackpot. Unlike fixed jackpots that pay the same amount every time, progressives increase until someone wins—then reset to a base amount and start growing again.

The Appeal

  • Life-changing jackpots possible
  • Excitement grows as jackpot climbs
  • Same gameplay as regular slots
  • Dreams of instant wealth

The Trade-off

  • Lower base-game RTP
  • Must bet max for jackpot eligibility (usually)
  • Jackpot odds are extremely long
  • Volatility is very high

Types of Progressives

Standalone Progressives

Single machines with their own jackpot. The jackpot only grows from bets on that specific machine.

  • Smaller jackpots ($1,000-$10,000)
  • Better odds of hitting
  • Found on older machines

Local Progressives

Machines within one casino linked together. Bets from all linked machines feed the jackpot.

  • Medium jackpots ($10,000-$500,000)
  • Moderate odds
  • Common in most casinos

Wide Area Progressives (WAPs)

Machines across multiple casinos in a network. IGT, Aristocrat, and other manufacturers run these networks.

  • Massive jackpots ($1M-$40M+)
  • Astronomical odds (1 in 50 million)
  • Famous games: Megabucks, Wheel of Fortune

How Jackpots Grow

When Progressives Make Sense

Play progressives when:

  • Jackpot is at historically high levels
  • You can afford max bet without straining bankroll
  • Entertainment value justifies lower base returns
  • You understand the odds are astronomical

Avoid progressives when:

  • You can't bet max coins
  • Jackpot is near reset value
  • You need better base-game returns
  • Your bankroll is limited

Must-Hit-By Progressives

Some progressives MUST hit before reaching a certain amount. When close to must-hit, these offer better expected value—though still likely negative.
