Tumbling Reels™
The origin of the chain reaction
The original brand for the 'cascading reels' feature, popularized by IGT, where winning symbols disappear and new symbols fall to create chain reactions.

Tumbling Reels™ is the unique brand name for the 'cascading reels' feature, popularized by the developer IGT (International Game Technology) through their slot 'Da Vinci Diamonds'. It can be considered the origin of the chain reaction mechanism, one of the most common features in modern slots.

The core of this feature is to trigger a chain reaction that allows for multiple wins from a single spin, where winning symbols disappear from the screen and new symbols fall from above to fill the empty spaces.

Forming a Winning Combination

First, a winning combination is formed on the reels through a regular spin.

Destruction of Symbols

The symbols that contributed to the win are removed from the screen with a disappearing animation.

New Symbols Drop

To fill the empty spaces, the symbols directly above them drop down to fill the gaps, and completely new symbols fall from the top of the screen to fill all the newly created empty spaces.

The Chain Reaction Begins

If the newly settled symbols form another winning combination, this process is repeated.

The chain reaction continues until no new winning combinations are formed.

Player Value

The Origin of Chain Reactions

This feature is a very important innovation in slot history, having become the direct foundation for numerous subsequent 'cascading reels' games.

Players can experience the primal fun of a chain reaction through IGT games.

Maximizing the Value of a Single Spin

Because the reel itself continuously creates a new game board, you can get multiple chances to win from a single bet, which maximizes the value of a player's bet.

The Thrill of Consecutive Wins

It provides the thrill of getting 2, 3, or even more consecutive wins from a single bet, which increases the immersion of the game.
