To trigger the Cascading Reels Feature, you'll need to hit a winning combination during the base game play of the TNT Bonanza online slot machine. First, all the winning symbols will be removed from the reels and all remaining symbols will fall down, taking their place accordingly—wherever possible. From here, new symbols will tumble into the vacant spaces for a chance to obtain an additional, or follow up, win. If you achieve a win, the same series of events will play out again. This process can occur multiple times until no new wins are generated from the initial cascade.
