Abstract
The present disclosure provides a method of controlling a probability of a probability-based item provision system, which includes measuring an amount of use of an item provision system during a first time interval, comparing the measurement result with a first threshold, and changing the probability of the item provision system within a predetermined range during a second time interval after the first time interval, based on a result of the comparing.
Claims17
A method for operating an item providing system of a game, the method comprising:
- providing information on a first probability of the item providing system during a first-time interval;
- in response to receiving a user input for using the item providing system during a first-time interval, selecting a first game item at random from among a plurality of candidate game items based on the first probability;
- providing the first game item;
- monitoring, in real time, a measured amount of use that the item providing system has been used during the first-time interval;
- providing information on the measured amount during the first time in real time;
- determining a first threshold amount of use that the item providing system has been used based on the measured amount;
- determining a probability range by comparing the first threshold to the measured amount;
- determining a second time based on the measured amount;
- changing the first probability to a second probability within the probability range for the second time interval;
- providing information on the second probability during the second time interval after the first-time interval;
- in response to receiving another user input for using the item providing system during the second time interval after the first-time interval, selecting a second game item at random from among the plurality of candidate game items based on the second probability;
- and
- providing the second game item, wherein the item providing system includes an item upgrade system, and wherein the amount that the item providing system has been used includes at least one of amount of goods used for item upgrade, a number of item upgrade attempts, and a number of users who attempt item upgrade.

- and
- at least one processor functionally coupled with the communication unit and the memory and configured to execute the stored instructions to:
- provide information on a first probability of the item providing system during a first-time interval;
- in response to receiving a user input for using the item providing system during a first-time interval, selecting a first game item at random from among a plurality of candidate game items based on the first probability;
- providing the first game item;
- monitoring, in real time, a measured amount of use that the item providing system has been used during the first-time interval;
- provide information on the measured amount during the first time in real time,
- determine a first threshold amount of use that the item providing system has been used based on the measured amount;
- determine a probability range by comparing the first threshold to the measured amount;
- determine a second time interval based on the measured amount;
- provide information on the second probability during the second time interval after the first time interval;
- in response to receiving a user input for using the item providing system during the second time interval after the first-time interval, selecting a second game item at random from among the plurality of candidate game items based on the second probability;
- and
- provide the second game item, wherein the item providing system includes an item upgrade system, and wherein the amount of use that the item providing system has been used includes at least one of an amount of goods used for item upgrade, a number of item upgrade attempts, and a number of users who attempt item upgrade.
The server of The server of wherein item providing system includes a Gacha system, and wherein the amount that the item providing system has been used includes at least one of an amount of goods used to purchase an item through the Gacha system, a number of purchases of the item through the Gacha system, and a number of users who purchase the item through the Gacha system.
A non-transitory computer-readable recording medium that records a program for causing a computer to execute a method, the method comprising:
- providing information on a first probability of the item providing system during a first-time interval;
- in response to receiving a user input for using the item providing system during a first-time interval, selecting a first game item at random from among a plurality of candidate game items based on the first probability;
- providing the first game item;
- monitoring, in real time, a measured amount of use that the item providing system has been used during the first-time interval;
- providing information on the measured amount during the first time in real time;
- determining a first threshold amount of use that the item providing system has been used based on the measured amount;
- determining a probability range by comparing the first threshold to the measured amount;
- determining a second time based on the measured amount;
- changing the first probability to a second probability within the probability range for the second time interval;
- providing information on the second probability during the second time interval after the first-time interval;
- in response to receiving another user input for using the item providing system during the second time interval after the first-time interval, selecting a second game item at random from among the plurality of candidate game items based on the second probability;
- and
- providing the second game item, wherein the item providing system includes an item upgrade system, and wherein the amount of use that the item providing system has been used includes at least one of an amount of goods used for item upgrade, a number of item upgrade attempts, and a number of users who attempt item upgrade.
