I would like to say thank you to all the participants! I really appreciate your effort and willingness to cooperate with us! In the upcoming days, we are about to add many new features and optimize the game in terms of speed. Once we do that we'll definitely start a new campaign. Stay tuned!
They run their affiliation weeks ago, improve the wagger contest, and new features as well as speed of dice (as lots of gamblers shared here).
Seems right, they have a lot of update and added some new feature on the wolf.bet last September 19, 2019

After 2 days of that new features and update added, the signature campaign has started to look some participants.
For sure they just waited this as what @Zwei said on last day of the first roud sig. campaign and they did this another new round of campaign. Very good job, wolf.bet team!
