[1] One of Ingersoll's signature figure 8 roller coasters was one of several attractions pulling in the crowds in the park's early days;[1][4] another was a looking-glass maze.

Each new ride was bedecked with lighting similar to that of the Luna Parks (not only of Coney Island but also Ingersoll's burgeoning empire in Cleveland and Pittsburgh).

Sandy (as mechanical rides were rapidly declining in popularity) was the bathing beach (with a six-story-tall diving tower), opened in 1910.

[1] With Coleman as president, the park added two large roller coasters (The Flash and The Thriller), installed Dodgem cars (a forerunner of today's bumper cars),[10] replaced the miniature railroad with a longer one, expanded the dancing pavilion and converted it into a roller skating rink, and housed the games and concessions in new concrete buildings.

Riverside Amusement Park's attendance increased after the end of World War II and the return of the region's troops to their home.

The residents of Indianapolis gained in mobility (due to greater availability of motor transportation) and in leisure activity.

The decade of the 1960s was not a kind one for Riverside Amusement Park, which was losing attendance for the first time since the end of World War II.

By the time John Coleman lifted the "whites only" policy (in response to a series of protests organized by the NAACP Youth Council in 1963),[15] the park was losing $30,000 a year.
