While this may not sound like much, remember that some of these progressive slots are featured at numerous casinos, and the amount being contributed to the main prize can rise very quickly. Typically, 1% of the amount being staked on the game goes into the prize pot although this can vary a little either way. This is possible because hundreds, possibly even thousands of people are playing the same slot game across all online casinos that feature it, and every time any of those players make a bet, a small portion is put aside into a 'pot'.
With a progressive game, there is a jackpot prize that grows and grows until one lucky player scoops the lot. In a normal slot, players make a wager, spin the reels and collect winnings independently of whatever any other player is doing. Progressive jackpot slots work in a slightly different way to regular games.
