# Lucky Box
Here’s an introduction to Lucky Box, which users need to obtain to participate in the Lucky Dice.
## 1. Lucky Box Display Cycle and Range

In SL:U, users get a chance to open a Lucky Box every 20 minutes. Early signs (thunder and lightning) appear 3 minutes before the Lucky Box activation, and **if not selected within 3 minutes after activation, the Lucky Box will be deactivated.**
**Lucky Boxes can be obtained up to 3 times per day**, and will be deactivated when the daily limit is exceeded.
Additionally, selecting a Lucky Box within the time limit rewards you with Lucky Dice tickets, with the amount determined by the Lucky Box's rank.
## 2. Lucky Box and Lucky Dice Ticket
Getting a Lucky Box rewards users with Dice Draw tickets(e.g., D-Rank)
As shown in the below, the number of Lucky Dice tickets awarded varies **according to the Lucky Box Rank.:**
| Lucky Box Rank | Number of Dice Draws |
| -------------- | -------------------- |
| E-Rank | 1 |
| D-Rank | 2 |
| C-Rank | 3 |
| B-Rank | 4 |
| A-Rank | 6 |
