It is not often that a game of slots is developed so well that the player will find themselves more interested in playing through the multiple levels of bonus games than they will in winning the slots. Gangster City is just such a game. The general flow of Gangster City takes the player through several different games. The first is the slot game, which in many ways is a standard game of slots. However, it is unlike slots in a few key ways: first of all, if the player spins and gets three bombs on any reels, they will receive a bomb, which will be important later. Second, the player has the ability to win access to a bonus game. The bonus game gives insight into the depth of Gangster City; in the bonus game, the player searches a room for keys. When the player finds all the keys, they are taken to another bonus game. Here, both the keys and the bombs come in handy, as the player is attempting to open safes, and both keys and bombs can be used. This game is comprehensive in its approach, succeeding as both a slot and as a tiered game.

Despite the multiple environments that this game spans, Playborne did not slack in creating a quality slot game. The slot is placed in an old suit case, with the game buttons built into the suite case front and sides. The icons featured are old cars, newspapers, safes, tommy guns, and bombs, among others. a slow jazz tune plays seamlessly through the experience. The game features customizable bet levels and betting lines. The primary difference in the slot on this game is that the player will want so much more than a simple winning spin, though if that is all they want, they will still find enjoyment in the game. They will want to collect bombs, and ultimately to find access to the bonus rounds, and that is what will drive the prolonged game play.

To access the bonus round, the player has to get three bonus symbols, at which time the player is notified with five gunshots across the slots that punctuate the identification of the entry into the bonus round. The bonus round takes the player to a room with many places they can search for keys by simply clicking. Searchable locations highlight when the player hovers their mouse over them, and if the play wants a guide to the possible locations, one is available in the game guide, always just a click away. The objective in the bonus round is to collect all ten hidden keys, hidden in twenty possible locations. The player can search for as long as they want, so long as they do not click three locations in a row that do not reveal a key. If they do not find the keys, they are taken back to the slots to play for the bonus round again--where the found keys will be tracked, but the unfound ones are reshuffled and all explored locations must be re-explored. However, when the player does find all ten keys, they are taken again to a new location--a room full of safes.

A dark room, a swinging light, and eight safes fill the room in the third game that is a part of Gangster City. The player's keys line the floor, and they can be used to open the safes. However, not all keys open a safe, and keys must be matched to the correct safe to open it. Another option is available to the player: as mentioned previously, up to three bombs can be collected from the reels. In the opened safes, the player will find one of four items: money, gold, bonds, or nothing. The final gamble in Gangster City is trying to find the safes that will open and reveal treasure. When the keys and bombs are used, the player returns back to the reels to play for bonuses, bombs, and the chance of winnings from the start again.

Gangster City is a classic game, with lots of flair. It's enjoyable to play because it has something to offer beyond the initial slots. The player will be hooked from the moment that they collect the first bomb or enter that first bonus game. This hook only increases at the game advances, and what will keep the player playing. Spinning the reels for winnings and bonus items, trying to find the keys while it storms in the background, or searching safes in the weak light of the basement, the player has something to play for all the way through Gangster City, and every play through will leave the player with something more to play for: more safes, more keys, and of course, the possibility of a winning reel.
