Server, communication system, method for controlling communication system, and program
A server includes drawing means for drawing an item by lottery from among an item group including a plurality of types of items with different scarcity values and providing the item to a user, and additional item providing means for providing an additional item to the user in accordance with a provision count of the number of times an item is provided by the drawing means.
1. A device comprising:
circuitry configured to
assign at least one item of an item group, the item group including a plurality of types of items with different scarcity values,
store, in a memory, a count of a number of times any item of the plurality of types of items is assigned,
assign a first additional item based on the stored count, and
when a predetermined condition is satisfied, assign a second additional item, in addition to the assigned at least one item, based on the stored count.
2. The device according to claim 1 , wherein
the first additional item has a higher scarcity value than any item in the item group.
3. The device according to claim 1 , wherein
the circuitry is further configured to assign the first additional item by including the first additional item in the item group when (i) the stored count reaches a predetermined count, and (ii) a time since the stored count reached the predetermined count is within a predetermined time.
4. The device according to claim 1 , wherein
the circuitry is further configured to transmit information on the stored count to a communication terminal.
5. The device according to claim 1 , wherein
the circuitry is further configured to assign the second item in accordance with the item that is drawn from among the item group.
6. The device according to claim 1 , wherein
as the stored count becomes higher, the scarcity value of the second item that is assigned becomes higher.
7. The device according to claim 1 , wherein
the circuitry is further configured to transmit information for displaying the first additional item or the second additional item to a communication terminal.
8. A method for controlling a device, the device including a memory and circuitry, the method comprising:
assigning, by the circuitry, at least one item of an item group, the item group including a plurality of types of items with different scarcity values;
storing, in the memory, a count of a number of times any item of the plurality of types of items is assigned;
assigning, by the circuitry, a first additional item based on the stored count; and
when a predetermined condition is satisfied, assigning, by the circuitry, a second additional item, in addition to the assigned at least one item, based on the stored count.
9. The method according to claim 8 , wherein
the first additional item has a higher scarcity value than any item in the item group.
10. The method according to claim 8 , further comprising:
assigning the first additional item by including the first additional item in the item group, when (i) the stored count reaches a predetermined count, and (ii) a time since the stored count reached the predetermined count is within a predetermined time.
11. The method according to claim 8 , further comprising:
transmitting, by the circuitry, information on the stored count to a communication terminal.
12. The method according to claim 8 , further comprising:
assigning the second item in accordance with the item that is drawn from among the item group.
13. The method according to claim 8 , wherein
as the stored count becomes higher, the scarcity value of the second item that is assigned becomes higher.
14. The method according to claim 8 , further comprising:
transmitting, by the circuitry, information for displaying the first additional item or the second additional item to a communication terminal.
15. A non-transitory computer readable recording medium having recorded thereon a program for a computer, the program causing the computer to execute a process, the process comprising:
assigning at least one item of an item group, the item group including a plurality of types of items with different scarcity values;
storing a count of a number of times any item of the plurality of types of items is assigned;
assigning a first additional item based on the stored count; and
when a predetermined condition is satisfied, assigning a second additional item, in addition to the assigned at least one item, based on the stored count.
16. The non-transitory computer readable recording medium according to claim 15 , wherein
the first additional item has a higher scarcity value than any item in the item group.
17. The non-transitory computer readable recording medium according to claim 15 , the process further comprising:
assigning the first additional item by including the first additional item in the item group, when (i) the stored count reaches a predetermined count, and (ii) a time since the stored count reached the predetermined count is within a predetermined time.
18. The non-transitory computer readable recording medium according to claim 15 , the process further comprising:
transmitting information on the stored count to a communication terminal.
19. The non-transitory computer readable recording medium according to claim 15 , the process further comprising:
assigning the second item in accordance with the item that is drawn from among the item group.
20. The non-transitory computer readable recording medium according to claim 15 , wherein
as the stored count becomes higher, the scarcity value of the second item that is assigned becomes higher.
