causing the control unit to

assign at least one of the reward items to each of the item boxes,

determine, based on the input of the player, whether or not an operation by the player in the game satisfies the determination condition,

if the operating is determined to satisfy the determination condition,

transmit, to the terminal device, image information for displaying the plurality of item boxes of the plurality of types simultaneously,

transmit, to the terminal device, image information a screen for providing the player with a reward item assigned to a part or all of the item boxes, and

transmit, to the terminal device, image information for displaying a screen for enabling the player to select whether or not the player uses or possesses a specific tool necessary for acquiring reward items assigned to all of the item boxes;

wherein the input unit receives, from the terminal device via the communication line, a second input of the player, the second input indicating whether or not the player uses or possesses the specific tool.

10. A computer-readable recording medium having recorded therein a process for causing a computer to execute actions comprising:

connecting, via a communication line, to a terminal device operated by a player, and providing a game including a predetermined event;

receiving, from an input unit, a first input of the player from the terminal device via the communication line;

storing a determination condition associated with the predetermined event, a plurality of reward items of a plurality of types, and a plurality of item boxes of a plurality of types;

assigning at least one of the reward items to each of the item boxes;

determining, based on the input of the player, whether or not an operation by the player in the game satisfies the determination condition;

if the operation is determined to satisfy the determination condition,

transmitting, to the terminal device, image information for displaying the plurality of item boxes of the plurality of types simultaneously,

transmitting, to the terminal device, image information for displaying a screen for providing the player with a reward item assigned to a part or all of the item boxes, and

transmitting, to the terminal device, image information for displaying a screen for enabling the player to select whether or not the player uses or possesses a specific tool necessary for acquiring reward items assigned to all of the item boxes;
