If the game freezes or closes and you cannot enter it, the first thing we suggest you do is to force the application to close. In many devices, you can enter the "Settings" section, then "Applications" and find the one you want to close, click on it and then on "Force stop". If after following these steps your problem is not solved, we invite you to contact us directly here.
Add to the message all the information that you consider valuable so that we can analyze the situation and resolve it as soon as possible. This can be the detailed explanation of the problem, the section of the game in which the error is presented or screenshots that help us understand it.
We will contact you as soon as possible so that you can continue enjoying the game without problems.
