The reward drop algorithm has been updated in version 1.217.1, to be more transparent and to minimize extremely unlucky outcomes for players.

The change includes the following adjustments:

2. One LG-4 per 104 Cases: A player cannot receive more than 1 LG-4 within a set of 104 Green Case openings.
