What are the best free sweeps slots to play

While there are many slots available for free at social casinos, we’ve selected four of the hottest ones you should play. Check out the table below for an overview of these titles.

Big Bass Mission Fishin

If you love the calmness of fishing, then you'll surely have the time of your life with this Pragmatic Play slot. It is one of the Big Bass installments featuring a 3x5 reel setup, 10 paylines, and a maximum 96.50% RTP.

The slot has very high volatility which means prize redemptions are less frequent but significant when you land them. You’ll find lots of features to make this possible including free spins, scatters, buy free spins, and Stack the Cash.

Place your hook in the right location and you can land up to 5,000x your spin!

Gates of Olympus

This is yet another ancient Greek-themed title from Pragmatic Play that takes you on an exciting journey with Zeus. The game takes place on a setup of 5 rows, 6 reels, and 96.50% RTP.

As expected, the operator has added many features to keep things fun. You’ll find tumbling reels, free spins, and orb multipliers of up to 500x your spin.

If you prefer, you can buy the free spins feature at a cost of 100x your spin. This makes it easier to redeem the maximum 5,000x your spin in prizes.

Book of Ra

Dive into ancient Egypt and explore hidden treasures with this title from Novomatic. The slot game keeps things simple with 3 rows, 5 reels, 10 paylines, and a decent RTP of 96.21%.

While checking out ancient Egypt, you can look forward to features like wilds, scatters, free spins, and expanding symbols.  If you have a huge risk appetite, try out the gamble feature. This lets you gamble your prize redemptions on a double-or-nothing spin.

Winning this spin lets you redeem double your cash prize; while losing means you forfeit it.

Starburst Galaxy

Starburst Galaxy is a sequel to the well-known Starburst slot by NetEnt. If you loved the first installment, this one does it better with the addition of new features. It has 5 rows, 5 reels, and 96% RTP. The slot maintains the same space theme but does not have any paylines.

When it comes to features, Starburst Galaxy has many. You’ll find wilds, Avalanches, a Mega Star, Feature Buys among others. One major difference between this and the original title is the maximum 25,000x on your lucky spin.
