What is an accumulator slot machine?

An accumulator slot is a game that builds up progress toward a bonus feature over time. Special symbols or values are collected across spins, and when enough have been accumulated, a bonus round triggers. Because this progress persists between players, advantage players can find machines where previous players left significant progress toward the trigger point.
