Here, the user terminal 110 may receive the first item array 710 selected by the user based on the winning probability or the item set status of the plurality of item arrays 710, 720, and 730.

For example, in FIG. 8A, the probability determiner 250 may cause the user terminal 110 to display the received plurality of item arrangements on the screen 810, and each of the plurality of item arrangements on the user terminal 110. The probability of winning or item set status may be provided to allow a user to select one of a plurality of item arrays based on the probability of winning or the item set status.

In an embodiment, the probability determination unit 250 may determine the cost of the selection attempt for one of the plurality of item arrangements 710, 720, and 730 based on the winning probability or the item set status to provide to the user terminal 110. Can be.

For example, the probability determination unit 250 selects a cost of attempting to select an item array having a winning probability of 0% or more and less than 10% and 10point, and selects a cost of selecting attempts for an item array having a winning probability of 10% or more and less than 30%. The cost of attempting to select an item array having 20 points, 30% or more, and 100% or less of winning probability can be determined as 30 points. Here, when the probability determiner 250 receives a selection for one of the plurality of item arrangements 710, 720, and 730 from the user terminal 110, the probability determination unit 250 may subtract a selection attempt cost for the corresponding item arrangement. That is, the probability determination unit 250 determines a selection attempt cost for an item array having a high winning probability, and determines a selection attempt cost for an item array having a low winning probability low, so that the user selects according to the winning probability. You can do that.

In one embodiment, the probability determination unit 250 determines the eligibility requirements for the selection attempt for one of the plurality of item arrangements (710, 720 and 730) based on the winning probability or item set status to the user terminal 110 Can provide. Here, qualification requirements may be determined based on the level of the game character.
