Lion Dance is released on PC via Steamandroid via the PlayStore. This allows you to try out new types of cards instead of using them all in the same time. However, once you have made it to that point, you can select something like the 'Get a Random Card' option to give you a unique card that can only appear once every other Lion Dance Slot. So, the final words here are that your first round in every Lion Dance Slot will be one of the same random ones.
The Dancing Lions Slot Machine is awarded two different levels in each of the 5 tiers. As you would think, this only applies to the bonus round items. When you receive new bonus round items, you may pick them up as normal or collect them by using them in one of the three Lion Dance Slot items (Cotton Candy, Black Magic Cuff or Snowman). This is the new bonus option from now on.
