Like any other company, Miniclip has a list of Terms and Conditions available to the public. You can find them below:
That being said, it's always a good idea to recall that players which accounts have broken these conditions may find them banned for several reasons, such as the use of 3rd party software, shared accounts, etc.
Miniclip reserves the right to ban these accounts from the game since their existence goes against our Terms, as we do not condone this type of behavior. As per our T&C:
You may be banned or have your account suspended or terminated if we think that you have not followed the Rules or if we believe in our sole discretion that you have behaved inappropriately whilst using our Services. In addition, if we believe you have engaged in cheating then we may remove any applicable Miniclip Coins from your account.
Regarding bugs or other issues that might occur in-game, it is uncommon for players affected by these to be compensated. We know you might find it unjust, but, as it is written on our T&C:
We do not guarantee that the Services will always be available or be uninterrupted, timely, secure or free from bugs, viruses, errors or omissions. For example, there may be times when the Services are unavailable due to maintenance or technical problems. We may also change, suspend or discontinue certain Services without giving you prior notice.
We will not be liable for any loss, damage or upset that you suffer as a consequence of any Service becoming temporarily or permanently unavailable.
If you have any issues regarding this, you can always contact us directly, by opening a ticket.
