Play 4Squad for Free

The 4Squad slot machine is a superhero-themed slot and although there are definite signs of Hollywood-inspiration in the art and in the superpowers, this squad of four heroes is not a team that you'll immediately recognize.

The lack of a big brand name is not an issue, though. The game is stylish, the art is stellar, and the interface is snappy and straightforward. Red Tiger Gaming has implemented a polished cluster-style slot machine that is easy to learn and satisfying to play.

As a 7-reel slot machine with 6 rows, 4Squad slot machine offers plenty of opportunities to win. Rather than simple paylines, the developer has opted for cluster play mechanics here. The objective is to get clusters of five symbols that touch horizontally or vertically. When you form a cluster, it will disappear, allowing the symbols above to tumble down, similar to the way things fall in Tetris.

Each time sets are found, the power meter for the hero associated with the match fills up. How much it fills up depends on the power of the symbol that was duplicated.

You can try your hand at the clusters and play 4Squad slot online for real money, whatever your budget. The minimum stake is just 0.20, and the maximum stake is 80.00.The max multiplier goes up to 1279.2, which is lower than some rival slots, but the more moderate reward is offset by lower risk since the overall volatility of this machine is lower. 4Squad online slot's RTP is 95.72%.

Although cluster play is enough to get our hearts racing, the bonuses are what really make the 4Squad slots game so exciting! The various colored symbols will trigger 4 different superhero features:

Green – Quake features: This knocks all the low symbols off the grid, allowing the grid to tumble and be re-filled with new and, hopefully, higher symbols.

Blue – Strike feature: This power randomly zaps symbols, turning them into wilds.

Red – Burst feature: Fill the red progress bar and this feature will clone randomly chosen symbols on the grid.

Yellow – Beam feature: This awards a random multiplier.

All four features can combine in the Superhero Mode feature too, where for one spin, all low pay symbols are removed, and each superhero will apply their modifier to the grid, giving you a potentially massive payout.

4Squad online slot is an unbranded machine, and it's a hugely entertaining free slot that can be fun to play for real money at your favorite online casino. However, there are plenty of other branded slot machines based on real superheroes, too.

Superman Last Son of Krypton from Amaya, as well as Playtech's Iron Man 3 and Captain America are all great comic book-inspired slot machines, although they all play on set paylines rather than clusters.

The visuals, performance, and RTP of the 4Squad online slot are all hero-worthy, and the bonus modifiers add another level of excitement. We also like the game's autoplay option, which allows you to set your bet and your budget, then just sit back and enjoy the machine in action.
