Just an fyi... for those who have accumulated coins without playing coin games....
Wgt issues or awards coins every time you level up. I believe it is 100 coins per level... so as soon as you log in to mobile all those coins are issued even if you never played on mobile for each level you have attained. If you are over level 100 well you likely have a little stash of coins.
You could easily estimate what you should have in an excell sheet.
100 + 200 + 300 .... ...... 10,000 at L100.
It is a slow grind but every desktop player has coins available as soon as they log in on mobile.
Mobile can play for credits in wgt tournaments... where sponsor apparel is disabled.
