Progressive slots vs regular

A progressive slot sets aside a portion of every bet into a jackpot that increases until someone wins it; a regular slot pays a fixed top prize that does not change.

Progressive: grows from a pre-set base value; regular: fixed top prize.
Funding
A fraction of each qualifying bet feeds the progressive meter.1
Regulation
UK Gambling Commission defines a progressive as an incremental prize from staked contributions.1
