They use the word total wager while they are showing my total wager from the start that makes it very confusing.
Most of the users will be confused as the way they are showing the progress percentages and wagering statistics. The best thing would be to not show the wagering statistics below the progress percentages for avoiding the confusions.
Agree that the wagering statistic and the progress percentage may make confusion for most people especially new players. '
I was confused as well when I saw it at the first time some time ago but I did not see it as a visual bug as I found the calculation just after I saw it for the first time when I went from rank 2 to rank 3.
I did not share it here because I think that the percentage progress is similar to the other casino where I play but showing showing it together with the wagering statistic which is counted from zero is not balanced with the progress percentage because it is not counted from zero.
So I have to agree that maybe coins.game can remove the wagering statistic or simply show the actual wagering starting from the newest rank with the wagering amount needed for the next rank.
