100₫ per paid game. Top up from 20.000₫ by VietQR bank transfer — no card needed, no plan that renews by itself.
With money in the wallet, nothing extra is charged: the coach for every game, hints, learn-from-mistakes, unlimited analysis, the evaluation bar when watching live.
When you start a paid game: 100₫ per game, even if it ends early. Games with Little Na, Uncle Tư and Teacher Lan are always free, and your first game with each paid character is a gift.
No. Play little and it lasts long; there are no monthly or yearly plans that renew by themselves.
Usually under a minute. The system recognises it by the transfer reference (the CVM code of the top-up).
With the CVM code in the reference, whatever you send goes into the wallet, even if it differs from the amount you picked (the minimum top-up of 20.000₫ applies when creating the order). If you forgot the reference, contact support with a picture of the transaction.
