Online, Slots, Wild, Jewels, Phoenix, Fire

Expanding wild slots are super exciting, giving you a big adrenaline rush when entire reels turn wild and winning combinations start appearing on the screen!

I decided to put together this list of seven of the best casino slots with expanding wilds (free and for money) to save you the time and effort required to find them. All these games have unique themes and features, but what they all have in common is expanding wilds in the base and bonus games.

As well as the games, I show you some of the best slot casinos to try them on. Ready to spin? I know I am!

At the Copa

  • RTP: 97.4%
  • Developer: Betsoft

At the Copa is a 3D Betsoft video slot with a salsa theme. You’ll see drums, trumpets, flamingos, maracas, and salsa dancers on the reels. As always with Betsoft slots, the graphics are detailed and intricate.

This medium volatility slot has a few features, including a free spins bound round and the ability to go double or nothing on your wins. However, I want to focus on the expanding wilds since that’s the main theme of this post.

The wild symbol is the moon over the ocean. When it lands in the center position on the middle reel, it will expand to fully cover it. This triggers an automatic free spin, and if a win occurs, you get another one with a 2x multiplier in play, then a 3x multiplier, and so on.

At the Copa is one of Betsoft’s best expanding wild slots. I recommend playing it at BetUS Casino with a 150% deposit match up to $3,000. This site offers a constantly updated library of video slots and supports crypto deposits and withdrawals.

Jungle Wild

  • RTP: 95.96%
  • Developer: WMS

There are lots of great slots set in Ancient Aztec and Mayan civilizations, and this is another one. You’ll see temples, sun gods, various tropical flowers, and creatures like parrots on the reels.

Jungle Wild has a free spins bonus round with up to 20 free games each time you trigger it. You can retrigger five additional spins by landing three or more scatters during this feature.

Best of all, on every spin in this game, two reels are covered with expanded wilds. The Jungle Wild symbol will cover two randomly chosen reels entirely, making it much easier to create winning combos.

Bubble Bubble 2

  • RTP: 96%
  • Developer: RTG

It’s difficult to go wrong with RTG slots, and Bubble Bubble was so popular that RTG released parts two and three. I’m focusing on the second one today. It has a spooky theme with pretty witches on the reels.

Bubble Bubble 2 has 50 paylines, and it’s all about wild symbols. Wilds can multiply wins by 3x; extra ghost wilds can appear on the reels, spreading to other reels as the witches cast spells, or expanding to cover the entire center reel as seven free spins play out.

You can play Bubble Bubble 2 and some other expanding wild slot games at Las Atlantis Casino. With a $9,500 welcome package and over 100 RTG video slots, you don’t want to miss out on what this US-friendly casino has to offer.

Piggy Riches Megaways

  • RTP: 95.07%
  • Developer: Microgaming

Megaways slots are all the rage these days, and with 117,694 ways to win powered by the unique game engine in this slot, it’s not hard to see why. This is a remake of the classic Piggy Riches slot. Cash, keys, golden tickets, and precious stones adorn the reels.

This game has a few noteworthy features. Cascading reels make it likely that one win is followed by another. There’s a free spins feature with up to 22 free games. However, the Mega Wilds are what we’re most interested in.

Mega Wilds can land on any reel, and when they do, they expand to cover the reel and provide multipliers of up to 7x. What do they look like? They’re the rich piggies in top hats, so you can’t miss them.

You can play this and other slot games with expanding wilds at Betway Casino. This is the ideal casino site for UK and Canadian players.

Wilds of Fortune

  • RTP: 96.3%
  • Developer: Betsoft

You might notice there are a few Betsoft slots on this list; that’s because they’re usually the best. This game is all about wild symbols, as the name suggests. It has a classic fruit machine theme with bells, bars, cherries, and diamond symbols on the reels.

As a classic slot, Wilds of Fortune is simple and only has one main feature; respins. They’re triggered when the expanding wild diamond symbol lands on any of the middle three reels. Each time this happens, you’ll get free respins until you land a winning combo.

You can play Wilds of Fortune and other free slots with expanding wilds at Wow Vegas Casino. There are over 300 exciting social casino games, and there’s a 5,000 coin welcome bonus for all new players.

Walk of Shame

  • RTP: 96.4%
  • Developer: Yggdrasil

Nolimit City is renowned for its quality video slots with awesome themes and unique features. Walk of Shame is one of its biggest hits. It’s themed on the night after a wild party with cocktails, shots, weapons, and people in compromised positions on the reels. It’s truly different!

Walk of Shame has 748 ways to win and multiple features, including a free spins bonus round, multipliers, and walking wilds. It also has expanding wilds, which is what I’m after. When character symbols land in view, they expand and award a multiplier. These are called loaded wilds.

You can play Walk of Shame and some other expanding wild casino slots at PlayAmo. It has a 100% welcome bonus worth up to $/€ 100 + 100 free spins, and it accepts players from most European countries.

T-Rex II

  • RTP: 96%
  • Developer: RTG

Expanding wilds don’t always go vertically on the reels, and this game is a good example of that. T-Rex II is a dinosaur-themed slot powered by Realtime Gaming, and you’ll see all the legendary dinosaurs, such as triceratops, suchomimus, and raptors, on the reels.

Info Box Icon

This slot has multiple features, including a free spins bonus round with up to 100 free spins at a time. Look out for the wild T-Rex that appears on the first reel. When he lands, he eats all the other dinosaurs, replacing them with new wilds. This can lead to absolutely epic winning combos.

You can play T-Rex II and more of the best online slots with expanding wilds at El Royale Casino. There’s a $7,000 welcome bonus, heaps of loyalty bonuses for players who stick around, and over 100 world-class slots to play.
