Mysbox Probability Explanation

Probability Mechanism

The probability, or called “Chance” in app settings, refers to the chance of receiving a specific item that is created and included in a mystery box created by Mysbox. “Chance” is created and calculated once a mystery box is created and activated.

The original probability (“Chance”) assigned to each item within a mystery box is determined based on the current inventory of that item at the time the box is created and activated. This initial probability shall be preserved and displayed publicly on the user’s storefront for transparency during the sales process. However, the probability may be adjusted internally via the application’s back-end should inventory levels fluctuate due to item sales, ensuring that subsequent calculations remain accurate and reflect real-time stock availability. This displayed probability may also be updated on the storefront if the user deactivates the active mystery box, modifies the inventory, and reactivates the box thereafter.

Post-purchase Unboxing Logic

Upon the buyer initiating the unboxing process, the system employs the Mersenne Twister algorithm—a widely recognized pseudorandom number generator—to produce a random integer within the range of 1 to 10.

For instance, you have a mystery box product including 3 items A, B and C within. Assuming the total quantity of this mystery box is 10 boxes, each item inventory will contribute to the total preset mystery box inventory and is subsequently presented like so:

  • Item A has 3 units in stock

  • Item B has 2 units in stock

  • Item C has 5 units in stock

Based on the Mersenne Twister algorithm, each linked item will be assigned a random number:

  • Item A has 3 items, so the random numbers are 1, 2, 3

  • Item B has 2 items, so the random numbers are 4, 5

  • Item C has 5 items, so the random numbers are 6, 7, 8, 9, 10

These values are then used to determine the item the buyer receives from the mystery box, based on the calculated probability (“chance”) of each item. Additionally, once an item has been selected from the mystery box, the system automatically decreases the item's available stock by one unit. It then recalibrates the numbering assignment for the remaining items based on their updated quantities. With this refreshed configuration, the random selection algorithm is executed again to ensure fairness in subsequent item allocations.
