Undefeated Xerxes Slot by Play'n Go: Review & Free Demo

Undefeated Xerxes Review

The blockbuster movie ‘300’ from 2006 depicted how a small group of fierce Spartan soldiers took on the whole Persian army with help from a narrow passage and their powerful shields. Undefeated Xerxes may seem like an odd title in that regard, but regardless of how you remember it, the Persian King Xerxes and his army won the battle. Play’n Go has come up with a stylish intro to the battle in this game, but its unique visual style does not extend to the gameplay.

You get Spartan soldiers, armor, swords, and shields on the grid, as well as King Xerxes as the bonus symbol. The base game is all about wilds and multiplier wilds, as well as wild transformation frames that appear at random times. These frames accumulate per wild that lands in the bonus round, building tension toward the final free spin reveal. This can lead to payouts up to 10,000x your stake, not least thanks to the x25 multiplier upgrade of the top-tier Spartan Hero symbol.

Play'n Go - Slot Developer

Play'n Go is a popular veteran developer that’s been in the game since 1997, and they have released more than 370 slots at this time. These are impressive numbers, and Book of Dead, Phoenix Reborn and Reactoonz are their most iconic releases so far.

Slot Theme And Storyline

Visually, the intro is the most impressive thing about Undefeated Xerxes slot, as it comes with a unique visual style that’s highly inspired by ancient Greek culture. The soundtrack creates the proper battle atmosphere, and the voiceover soundbites will inspire you to soldier on.

Undefeated Xerxes RTP, Volatility, And Max Win

The top-tier Undefeated Xerxes RTP of 96.20 % is a bit above average. However, operators can adjust the RTP down to 94.20, 91.20, 87.20, or 84.20 %, depending on the market. This is a high volatility installment from Play’n Go, so expect fluctuations on your bankroll in longer sessions. The Undefeated Xerxes max win is 10,000x your stake, which is above average, and it comes with a 1 in 100 million spins hit rate.

Undefeated Xerxes Bonuses And Special Features

You get a taste of the wild frame system in the bonus round via the random wild frames in the base game, and Undefeated Xerxes slot also comes with multiplier wilds. Let’s check it all out!

Wilds & Multiplier Wilds

Both Wild symbols and Multiplier Wild symbols substitute for any pay symbol, and multiplier wilds come with values of x2 to x5. The multipliers are added together if more than one multiplier wild is part of the same win, and the total multiplier will boost the win.

Wild Frames

You can get 3 to 4 Wild Frames at random times during base game play, and these frames are placed over random positions on the grid. Regular wild frames turn into wilds, while upgraded wild frames turn into random multiplier wilds.

Undefeated Xerxes Free Spins

The Bonus Round triggers by landing 3 bonus symbols anywhere in view, awarding 10 free spins. You can get 2 scatters randomly on reels 1 and 2 via the guaranteed scatter feature, which may help trigger the bonus round. Landing 3 scatters awards 1x your stake upfront, before the Undefeated Xerxes free spins no deposit play out.

There is no way to win extra spins or retrigger the bonus round, and all wilds that appear will frame their respective positions. Wilds landing in a framed position upgrades the frame to a multiplier wild frame. The frames remain in place until the final free spin, where regular frames reveal wilds and upgraded frames reveal random multiplier wilds. The top-tier Hero Symbol is upgraded with an x25 multiplier for the final free spin.

Review Summary And Verdict

We enjoyed the distinct visual style you get in the Undefeated Xerxes intro, and perhaps it would’ve been a better idea to keep those visuals in the game as well. It would’ve been more risky, sure, but at least the game would stick out a lot more than it does. Don’t get us wrong, the graphics are solid as usual from Play’n Go, but hardly very original. The gameplay offers nothing new either, and getting only 3 to 4 wild frames in the base game feels a bit tame for a game about such fierce soldiers.

Increase the number of random wild frames to 5-10 and the base game would be that much more exciting. It’s hardly pulse-raising as it is, however, and the same can be said about the bonus round, at least until the final spin. Accumulate enough wild frames, and especially multiplier wild frames, and the final spin will be a heart-stopper with its 10,000x potential. The x25 Hero symbol multiplier helps as well, but even full grid wins top out at only 180x your stake without wild multipliers or the elusive Hero symbol involved.

Strategy And Tips For Winning

Your overall Undefeated Xerxes strategy should include playing the top-tier RTP version of the game.

A strategy we like to play with is to guess when the bonus round is about to hit. We raise the bet level a bit when we feel it's overdue, but this can be risky if you get too hooked on the chase.
