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 server comprising:
a memory, which stores (i) an item group including a plurality of types of items with different scarcity values, and (ii) a provision count of the number of times an item is provided to a user, and
a processor,
wherein the processor:
in response to a request from the user, draws an item from among the item group stored in the memory, and provides the item to the user; and
increases the possibility of acquisition of an item with a scarcity value more than a predetermined value within the item group by the user when the provision count of the number of times reaches a predetermined count.
2. The server according to claim 1 , wherein the processor includes the item, with the scarcity value more than the predetermined value, in the item group in accordance with the provision count.
3. The server according to claim 1 , wherein the processor provides the item with the scarcity value more than the predetermined value to the user by including the item in the item group when (i) the provision count reaches a predetermined count, and (ii) a time since the provision count reached the predetermined count is within a predetermined time.
4. The server according to claim 1 , wherein the processor transmits information on the provision count to a communication terminal of the user.
5. The server according to claim 4 , wherein the processor provides another type of item to the user in accordance with the item that is drawn from among the item group.
6. The server according to claim 5 , wherein
as the provision count becomes higher, the scarcity value of the another type of item that is provided becomes higher.
7. The server according to claim 1 , wherein the processor provides another type of item to the user in accordance with the item that is drawn from among the item group.
8. The server according to claim 7 , wherein
as the provision count becomes higher, the scarcity value of the another type of item that is provided becomes higher.
9. A method for controlling a communication system comprising a server and a communication terminal of a user, the server including (i) a memory, which stores an item group including a plurality of types of items with different scarcity values, and a provision count of the number of times an item is provided to a user, and (ii) a processor, the method comprising the steps of:
(a) transmitting, by the communication terminal, an item acquisition request to the server;
(b) in response to the item acquisition request from the communication terminal, drawing an item from among the item group stored in the memory, and providing the item to the user, step (b) being performed by the processor;
(c) increasing the possibility of acquisition of an item with a scarcity value more than a predetermined value within the item group by the user when the provision count of the number of times reaches a predetermined count, step (c) being performed by the processor.
10. The server according to claim 9 , further comprising the step of:
(d) including the item, with the scarcity value more than the predetermined value, in the item group in accordance with the provision count, step (d) being performed by the processor.
11. The method according to claim 9 , further comprising the step of:
(d) providing the item with the scarcity value more than the predetermined value to the user by including the item in the item group when (i) the provision count reaches a predetermined count, and (ii) a time since the provision count reached the predetermined count is within a predetermined time, step (d) being performed by the processor.
12. The method according to claim 9 , further comprising the step of:
(d) transmitting information on the provision count to a communication terminal of the user, step (d) being performed by the processor.
13. The method according to claim 12 , further comprising the step of:
(e) providing another type of item to the user in accordance with the item that is drawn from among the item group, step (e) being performed by the processor.
14. The method according to claim 13 , wherein
as the provision count becomes higher, the scarcity value of the another type of item that is provided becomes higher.
15. The method according to claim 9 , further comprising the step of:
(d) providing another type of item to the user in accordance with the item that is drawn from among the item group, step (d) being performed by the processor.
16. The method according to claim 15 , wherein
as the provision count becomes higher, the scarcity value of the another type of item that is provided becomes higher.
17. A non-transitory computer readable recording medium storing instructions for a computer functioning as a server in a communication system including the server and a communication terminal of a user, the server including (i) a memory, which stores an item group including a plurality of types of items with different scarcity values, and a provision count of the number of times an item is provided to a user and (ii) a processor, the instruction causing the computer to perform the steps of:
(a) in response to an item acquisition request from the communication terminal, drawing an item from among the item group stored in the memory, and providing the item to the user;
(b) increasing the possibility of acquisition of an item with a scarcity value more than a predetermined value within the item group by the user when the provision count of the number of times reaches a predetermined count.
18. The non-transitory computer readable recording medium according to claim 17 , the instruction causing the computer to further perform the step of:
(c) including the item, with the scarcity value more than the predetermined value, in the item group in accordance with the provision count.
19. The non-transitory computer readable recording medium according to claim 17 , the instruction causing the computer to further perform the step of:
(d) providing the item with the scarcity value more than the predetermined value to the user by including the item in the item group when (i) the provision count reaches a predetermined count, and (ii) a time since the provision count reached the predetermined count is within a predetermined time.
20. The non-transitory computer readable recording medium according to claim 17 , the instruction causing the computer to further perform the step of:
(e) transmitting information on the provision count to a communication terminal of the user.
21. The non-transitory computer readable recording medium according to claim 20 , the instruction causing the computer to further perform the step of:
(g) providing another type of item to the user in accordance with the item that is drawn from among the item group.
22. The non-transitory computer readable recording medium according to claim 21 , wherein
as the provision count becomes higher, the scarcity value of the another type of item that is provided becomes higher.
23. The non-transitory computer readable recording medium according to claim 17 , the instruction causing the computer to further perform the step of:
(f) providing another type of item to the user in accordance with the item that is drawn from among the item group.
24. The non-transitory computer readable recording medium according to claim 23 , wherein
as the provision count becomes higher, the scarcity value of the another type of item that is provided becomes higher.
