Chimney Stacks with a Mary Poppins Theme

Bally Technologies have developed an online and mobile version of Chimney Stacks, a slots game that has long been popular in real-world casinos. Set on the snow-bedecked rooftops of London, the game’s design gives a nod to the chimney-sweep sequence in Mary Poppins, and has an elegant, slightly Victorian look.

The game plays on five reels containing four rows, with 40 bet lines. These bet lines are “fixed”, meaning a player must play all 40 of them on every spin, but players do have a wide range of options when setting the bet per line, so the total bet per spin ranges from as low as 0.40 coins, to as many as 500 coins. The object of Chimney Stacks, as with most slots games, is to match three or more identical symbols on a bet line, running consecutively from the left-most reel. As it has been designed for mobile play, Chimney Stacks is easily accessible to players on mobile devices, whether they are using an iPad, iPhone, or Android-enabled tablets and smart phones.

Sticking to Straightforward Icons

Chimney Stacks employs a small range of simple symbols. There are the standard low-win poker symbols: 9, 10, J, Q, K and A. The game has only three medium-value icons: a weathervane, a chimney brush with bellows, and a top hat.

The wild symbol is simply the word “Wild” emblazoned on the city skyline, and the “Free Games” scatter icon is equally straightforward. An attractive feature of the game is the ability (even in base-play mode) of the wilds to stack, and fill an entire reel, which increases the possibility of winning bet lines. Apart from set payouts for specific combinations, Chimney Stacks also has two progressive options that give players a shot at extra-large jackpots, if they decide to play in either the Three Level Optional Internal mode or the Super Progressive Enabled mode. Of course, to win the largest possible payouts, players need to be betting the maximum on every spin. The most useful feature, from a player’s point of view, is the variety of bonus options.

Stacked Wilds and Free Game Bonuses

If a player scores three “Free Games” scatter icons anywhere on reels one, three and five, it activates the free spins bonus feature. The player then gets 10 free spins, with all wins during the bonus round increased by a 4X multiplier. If two or more stacks of wilds occur during base play, free spins are also triggered.

The difference is that any stacked wilds will remain in place throughout the free spins, generating even more winning bet lines and multiplying the wins on them by 4X. With two or more wild stakes locked in position for an entire free spins round, the wins can become enormous. If two or more stacks of wilds appear when the free spins bonus round is already in progress, they will remain locked in place for the rest of the bonus round, again helping the player rack up some sizeable wins.
