The processing unit 113 will respond to the complaint request to control the checking unit 114 to start the verification program for secondary verification. In another preferred embodiment, in addition to the artificial intelligence processing module of the verification unit 114 for verification, the case can also be manually checked by the background verification administrator. In another preferred embodiment, if the winning result determined according to the complaint is consistent with the previously set winning result, the original bonus allocation information is maintained and payment is made. If the winning result determined according to the complaint is inconsistent with the previously set winning result, new bonus allocation information is generated and payment is completed based on the winning result, allocation rules, and the value of the amount of transaction media sent by each terminal device.

FIG. 3 shows the time points of the check from the start to the pre-payout check unit according to a preferred embodiment of the present invention. In other words, the present invention will perform the first check when the user edits the betting game in the betting game editing interface 1121 to start the game, to determine whether the betting game content complies with the regulations, and only if it complies will the opening bet be made. Then, after the betting game is closed and the user enters the result in the betting game editing interface 1121, the second check will be performed to determine whether the written result complies with the facts, and only if it complies will the input result be announced. After the input result is announced, in order to avoid subsequent disputes, this case also provides participating betting users with the opportunity to appeal against the input result or the bonus distribution information, and executes a third check based on the appeal request to determine the final win or loss result, and then generates distribution data and completes payment based on the win or loss result, distribution rules, and the value of the amount of transaction media sent by each terminal device. It is worth noting that the execution of the above-mentioned check can be performed by the artificial intelligence processing module of the check unit 114, or by the background check administrator to perform manual check, or by the artificial intelligence processing module of the check unit 114 and the background check administrator at the same time, and this case does not limit the execution method. Furthermore, the above-mentioned execution check time point is only an example. In other embodiments, the check time point can also be adjusted according to needs. For example, during the betting period, the artificial intelligence processing module of the check unit 114 checks the user's betting qualifications to prevent unqualified people from defaulting on their bets. In a preferred embodiment, in order to prevent anyone from defaulting on their bets, the points can be recorded and noted in the user's record.

Once the facts are met, in step 422, the input result and the bonus distribution information are made public. The input result and the bonus distribution information generated according to the input result are made public. In a preferred embodiment, the processing unit 113 responds to the verification result of the verification unit 114 that the input result is met, and the input result and the bonus distribution information generated according to the input result are made public on the betting interface 1122.

On the contrary, if the input result does not conform to the facts, in step 424, the input result is corrected. The user of the betting game operator is required to correct the input result. In a preferred embodiment, the processing unit 113 responds to the verification result of the verification unit 114 that the input result does not conform to the facts, and sends a notification message to require the user of the betting game operator to correct the input result. And in step 420, the corrected input result is re-examined to determine whether the corrected input result is true.

After the input result is announced, in order to avoid subsequent disputes, this case further provides a complaint step. In step 426, the input result and the bonus distribution information are rechecked according to a complaint request. In a preferred embodiment, the final input result and the bonus distribution information generated according to the input result are rechecked according to a complaint request from the betting user. In a preferred embodiment, in addition to the secondary verification by the artificial intelligence processing module of the verification unit 114, manual verification can also be performed in conjunction with the background verification administrator.

In step 428, the lottery is distributed according to the complaint result. In a preferred embodiment, if the winning result determined after the complaint is consistent with the previously set winning result, the payment is made according to the original lottery distribution information. If the winning result determined after the complaint is inconsistent with the previously set winning result, new lottery distribution information is generated and the payment is completed based on the winning result, distribution rules, and the value of the amount of the transaction medium sent by each terminal device.

In a preferred embodiment, each user of the game system 100 has his own account, which can be applied for through the game system 100, or directly created using a social networking site, such as Facebook, Yahoo, Google, Line account. Therefore, the user can directly invite all members to participate in the betting game through the social networking site, or only invite friends to participate in the betting game according to the friend list created by the user on the social networking site.
