If the rolls were pure random rolls whatever happened before doesn't matter at all for what will happen next.

If you roll a dice and you get a 6, do you think is less likely to get again a 6 the next dice just because the previous one had that outcome?

that said is hard to say how the rolls in this game really work.

Hi! It is based on random chance and what someone else does will not affect your chances. Some events have ninjas rarer than others, but based on feedback, the events have been improved greatly and chances increased.
