This is a more complex arrangement of dominoes involving several subsequent splits such that all of the end points topple at the same time. The key idea is to make both lines after a split have the same length before splitting them again. The effect of all end points toppling together can be emphasized by adding a bell at each end to create a loud sound together.

Since each split turns one toppling domino line into two, the total number of end points is $$2^c$$ where c is the number of corners on the path from the start to one of the end points.
