I have used this app for 4-5 months in 2018 because this year the app was removed by Google play store and the tournament system inside the app in every game was changed .
I have 300 tokens now in 3 account so total was 900 tokens before few months I was playing the runout game in mpl with 30tokens and I easily score 700-1000 score and win 10rs.
So 900 tokens = 30 times and I will win 300rs .
But they knew it that the token system will ruined their business so they removed that and now there was only 1v1 battle in every game and I have to play with real money not tokens.
I think it is now a game of gambling only.
So don't waste your money in this Battles because in starting the matching will be with lower rank but when you earn 50rs they will match you with hackers or with hight ranks .
Hackers are now in everywhere in online games and in mpl also you will face hackers but you can't identify them because you can't see their prospective of gameplay so better stay out of this and try some different apps.
