This node implements the "tumbling reels" or "cascade" mechanic.
The Cascade The Reels node removes winning symbols and drops new ones from above.
The Cascade The Reels node takes the current state of the reels and the details of winning lines. It removes the symbols involved in wins, shifts the remaining symbols down (simulating gravity), and fills the empty spaces at the top with new random symbols.

Usage
Cascading Wins
- After a win is processed and paid out, trigger Cascade The Reels.
- Use the new Reels output to update the game view.
- Loop back to Check Wins with the new reels to see if the cascade created new wins (chain reaction).
Detailed Behavior
- Gravity: Symbols above a removed symbol fall down to fill the gap.
- Refill: New symbols are generated at the top.
- Weighted Refill: If Symbol Weights is provided, it uses them to randomly select new symbols. Otherwise, it picks uniformly from the unique symbols present in the input.
Troubleshooting
- Not Clearing: Ensure Winning Lines Details contains the correct position data.
