How does dota calibration works?
We will assign one of our boosters to play calibration matches on your account according to your previous season mmr. Booster will finish calibration matches so you will have MMR on your account.
Who will work on my account?
According to your previous MMR we will assign a booster who has at least 1000+ more MMR on his main to make sure winrate, KDA etc. higher than average.
What if calibration winrate will be low?
In case you choose “winrate guarantee” option we will inform you about it and will be ready to refund or do bonus mmr on your account.
What MMR can I expect after calibration?
Valve doesn’t disclose calibration formula information but we need know that previous mmr, winrate, kda, damage and other numbers are important. Our boosters know how to get best result from every calibration match.
Why z3dota?
Safe and anonymous boosting

We have very strict rules for our boosters:

- they are not allowed: communicate with anyone from friendslist

- inform anyone that account is being boosted to get mid/carry position;

- add/remove friends

Also, we care about account safety and we will guide you how to secure your account before we start boosting - player won’t be able to trade or change account email/pass.

You can check yourself how it works! Try to change password or send some items from our account: johnson_53 pass: Hui87786YWKGF
Insecure and unsafe boosting

You can find many ‘self-employed’ boosters on the Internet who never follow any rules while boosting.

You have probably met some of them while playing - they spam in chat that they are boosting, they can easily reply to someone from your friends list or play online/stream your order without noticing you.

Professional boosters

We hire only the most skilled DotA2 boosters in order to complete every order with maximum speed and highest win rate possible. We are the only Dota2 boosting service which can offer TOP1 MMR Boosting.

Random boosters
Hiring random boosters results in random boosting quality. Most of dota 2 boosting service providers unable to complete boosting orders higher then 6000 mmr with stable and high win rate.
Secured payments

Z3DDOTA are verified by G2A PAY - one of the leading payment processing operator from G2A.COM marketplace.

Every payment is being protected and confirmed by G2A PAY which makes it save for both parts.

Direct payments

In order to be verified by a payment processing company you need to pass a strict procedure and be approved by their security team.

That’s why many of boosting services and self-employed boosters work only with direct payments which makes it unsafe for every customer.

Guaranteed deadline

Z3DDOTA is the only Dota2 boost provider that guarantee deadline of every order. If we fail to do so we will refund our customer 30% back and still complete the order. (not applicable for orders with pick/ban hero)

No guarantees

There is no guarantee that order will complete on time in specified deadline. It means in case of delay customer unable to receive any kind of refund.

Order tracking, communication with the booster

  2. Detailed order stats: Our system allows to provide detailed stats about every game booster played. You can easily track booster’s performance on your order.
