A continuous process wherein polymers or polymeric materials can be subjected to multiple sequential processing systems of differing temperatures and process conditions to synergistically enhance the pelletization and conditioning of those polymers and polymeric formulations, dispersions, and solutions. A signal detector for detecting an input signal and adapted to compensate for timing misalignment is also disclosed. The frame preferably defines the periphery of the reel structure. The group sizes are within certain preferred ranges, designed to minimize the risk of premature bingos and thus to increase jackpot size and player excitement.
