Online Slots Featuring Expanding And Stacked Symbols

Online slots have a practically endless range of themes. Since symbols are designed to fit the theme, they can come in all sorts of shape, size and colour. While symbols have countless different appearances, they also have a number of different features.

Two features in particular that go down well with players are expanding and stacked symbols. These are popular because they can add more high-paying symbols to the grid and can improve your chances of winning.

If you’re keen to find out more about how these features work, keep on reading.

How Expanding And Stacked Symbols Work

We’ll have a look at expanding symbols first of all. As the name suggests, these are symbols that can expand and take over other positions on the grid. Most of the time, they expand vertically and fill a reel, though some can expand horizontally as well. Expanding symbols can be wilds or standard symbols - it depends on the slot. For some slots, symbols can only expand during the bonus round.

As for stacked symbols, these are matching symbols that land stacked on top of each other and are more than one position high. A lot of the time, these symbols can fill an entire reel when they land. Just like with expanding symbols, both wilds and standard symbols can be stacked. Both a slot’s base game and the bonus round can have stacked symbols, though some slots may just have them appear during the bonus round.

Both of these features are quite similar in that they involve having the same symbol appear on more than one position on a reel - or a full reel. They can improve your chances of winning, especially if the symbol that expands or appears stacked is a wild. Now you know how these features work, it’s the perfect time to play some slots with expanding and stacked symbols!


Play Amazing Slots With Expanding And Stacked Symbols


If you want to see the expanding reels feature in action, have a go at the Sahara’s Dreams slot from Fugaso. This Arabian-themed slot has a free spins round that’s triggered by landing three or more wild scatters. You’re given 10 free spins and while these are in play, one of the slot’s high-paying symbols is chosen to become the expanding symbol. Should this symbol land, it will expand to fill the reel it’s on if doing so will give you a win.

There’s also Sword Of Khans by Thunderkick, which also has a free spins round where a standard symbol can expand to fill an entire reel. Highway To Hell Deluxe from Wazdan and Pearl Of The Orient from iSoftBet are both worth a mention too, especially since these two slots have wilds that can expand.

Mighty Arthur Slot featuring both Expanding and Stacked Symbols

As for slots with stacked symbols, there are quite a few of them you can play here at AUSlots. A good example is Tractor Beam by Nolimit City, a slot themed around alien abductions on a farm. A randomly triggered feature adds stacks of matching farm animal symbols onto up to four reels, potentially giving you a large win.

Another one worth playing is Aus Dem Tal, a mining-themed slot from Endorphina that has stacked wilds appearing during the free spins round.

There’s also Sheriff Of Nottingham from iSoftBet and Ticket To The Stars from Quickspin, both of which also have expanding wilds.

If you’re after a slot that has both expanding and stacked symbols, try Mighty Arthur from Quickspin. Arthur appears as a wild that’s stacked three positions high. Whenever this wild lands on reel 3, it expands horizontally in both directions, effectively turning both reels 2 and 4 into fully wild reels.
