on their site in FAQ section there is answer about it:
Q: What are the consequences if the connection breaks down while I am in the middle of a progression? Top
A: The programming of our software is such that these breaks do not affect your game. On the one hand, no data will be lost since they are stored on our server. If you want to check on a certain game, you will always be able to do so. Please send us an email telling us the game you played, when you played (please also add if your local time or ours), then we will be able to give you the required information. On the other hand, and for you this might be the more important factor, you are practically able to reenter the game wherever you left it, afterwards. In our online casino, each gambler has his own table to which he comes back after a connection break-down, i.e. the random generator will basically continue from where it was forced to stop by the connection break-down. The only exception to the rule: You chose to continue playing at another table after you restarted the game. As soon as you continue playing, the random generator will be running.
