Generally, the bidding game will first define a range, such as 1-50 cycle, and the bidding 50 will automatically start from 1. Secondly, the qualification rule is that if it is a multiple of 3.7, it means that multiples of 3 and 7 have to pass, and ordinary multiples have to pass. Specifically, it is 1.2. Guo. 4.5. 8. Guo 10. 1. Guo. 13. Guo 16. Wait, wait, wait. That is to say, it should pass 3.6.7.9.12.14.15, and so on. Generally, in order to increase the difficulty, we will add one every 3.7 times in addition to the multiple. That is, numbers with 3 or 7 should also be passed. For example. 1.2.guo. 4.5. 8. Guo 10. 1. Guo. Guo. Guo. Guo. 16. The difference is that the original 13. 17.3 1 can be counted, but it can't be counted after 3.7. Because there is 3.7 in the number. However, the rules can be modified according to the number of people and the difficulty requirements, and there is no particularly hard and fast regulation. Hope to adopt.
