The American Gangster Slot Machine is simple in design, using two-dimensional rendering to present a series of characters against the background of the late night city. However, even though it looks basic on the surface, these graphics can really evoke the retro vibe of the game. For example, using high-contrast shadows on character symbols helps to imitate old noir mafia movies, while other symbols are appropriately bold to add a bit of glitz and charm.
Some very basic animations are also involved-each time a winning sequence is arranged, the character symbols will move subtlely. It's nice to see more moves, but then again, this was set in the 1920s. If you have seen any film noir, you will know that everyone was as rigid as a board at the time.
