T.N.T. / Rock On / Boogie / Dyn O' Mite

The pinball machines "T.N.T.," "Rock On," "Boogie," and "Dyn O' Mite," produced by Allied Leisure Industries in the mid-1970s, share similar designs and gameplay features. "Rock On," released in September 1975, is a four-player solid-state electronic game featuring two flippers, one pop bumper, two slingshots, eight standup targets, four solitary drop targets, and left and right outlane detour gates. The playfield art includes a likeness of 1970s American television actor Jimmy Walker, known for his catchphrase "Dyn-o-mite!" 

"Dyn O' Mite," a two-player version released in 1975, shares the same playfield layout and artwork as "Rock On."

In 1976, Allied Leisure re-released the four-player version as "T.N.T."

Later in 1976, another re-release titled "Boogie" was introduced, maintaining the same gameplay and design elements.
