I am a programmer, and I think tencent games's randomness is pseudo-randomness.
How can I put it? That is to say, suppose the probability of winning every prize is 1%. If you charge a lot of money, Tencent will judge you as a Kryptonist, and the system will automatically adjust your probability to 0. 1%.
If you are a new account, Tencent may also adjust your probability to 10%.
It also has something to do with the online time of the account. Is it an old player or something?
According to the rule I summarized, if your account number is more than 20, or if you have charged money, I don't recommend you to smoke Athena. Not cost-effective. But if you think it's worth changing the inscription for gold coins, you can also try it.
PS: Don't smoke, smoke, play a game, or log in again. Good luck.
