The War of the Worlds Slot Review - Gameplay, Features & Free Play

The War of the Worlds is a licensed video slot that brings H.G. Wells' Martian invasion to a 5-reel, 100-payline grid. It pairs expanding wilds and scatter symbols with a multi-scene bonus round where you command cannons against the invaders. This review covers the game's RTP, volatility, features and where it sits among other sci-fi slots.

The War of the Worlds Slot - Editor's Comment

The War of the Worlds is one of those licensed slots that tries to do more than simply paste a famous name onto a standard reel set. The game leans into its source material with expanding wilds, a scatter symbol and a bonus round that asks you to command cannons against Martian invaders. The 100-payline layout gives it a busier feel than many five-reel games, and the animation and sound are designed to build as wins land.

The published RTP of 93.54% is below the average for modern video slots. The game's medium volatility and 100-payline layout give it a distinctive feel compared with many five-reel titles.

A news item on Casino City dated 22 July 2010 reports that Virgin Games launched a new slot machine, though the source does not explicitly confirm it was The War of the Worlds. The graphics and sound design reflect an earlier era of online slots.

What We Liked

  • The multi-scene bonus round is more engaging than a standard free-spins feature.
  • Expanding wilds substitute for other symbols and can help complete winning lines across the 100 paylines.
  • The licensed theme includes music and imagery that fit the H.G. Wells story.
  • Autoplay is available for continuous spinning.

What is The War of the Worlds Slot?

The War of the Worlds is a five-reel, 100-payline video slot. It is officially licensed and includes music and imagery inspired by the H.G. Wells novel. The game uses expanding wilds, scatter symbols and a bonus round where players command cannons to destroy Martian invaders. A news item on Casino City dated 22 July 2010 reports that Virgin Games launched a new slot machine, though the source does not explicitly name The War of the Worlds.

The slot is listed with a 93.54% return to player and medium volatility on VegasSlotsOnline. That RTP is a long-run theoretical average, not a prediction for any single session. The game's layout and features are typical of its era, with a focus on narrative-driven bonus play rather than complex mechanics.

There is a discrepancy in the available sources regarding the game's developer. VegasSlotsOnline lists it as an Ash Gaming title, while Casino City lists the software providers as GTS and Playtech. We have not been able to resolve this conflict, so players should check the game's own credits or the casino's information for definitive attribution.

The 100-payline structure means all lines are active on every spin, so the total stake is spread across them. The expanding wild can help complete multiple paylines at once. The bonus round is a multi-scene sequence.

The War of the Worlds Slot RTP, Payout and Volatility

The published return to player for The War of the Worlds is 93.54%, with medium volatility. This RTP is lower than many modern video slots, which often sit between 95% and 96%. A lower RTP means the game is theoretically less generous over a very large number of spins, though individual sessions can vary widely.

Medium volatility is a published characteristic of the game. The expanding wilds can help complete winning combinations when they land on the reels. As with all slots, the outcome of any spin is determined by a random number generator, and no strategy can change the odds. The RTP is a long-run average, not a guarantee of what you will experience in a session.

How to Play The War of the Worlds

Playing The War of the Worlds is straightforward. The game uses a standard five-reel layout with all 100 paylines active. Here is a step-by-step guide:

  1. Set your total bet per spin using the controls at the bottom of the screen. The minimum and maximum bets are not specified in the available information, so check the game interface for the exact limits.
  2. Press the spin button to start the reels. You can also use the autoplay feature to spin a set number of times without interruption.
  3. Winning combinations are formed by matching symbols on active paylines from left to right. The paytable shows the value of each symbol.
  4. The wild symbol expands to cover the entire reel it lands on, substituting for other symbols to help complete winning lines.
  5. Scatter symbols can trigger the bonus round. The exact number required is shown in the paytable.
  6. During the bonus round, follow the on-screen prompts to command cannons and destroy Martian invaders.

Results in the base game are determined by a random number generator. The bonus round may involve choices, but the available information does not specify whether these choices affect the overall return.

The War of the Worlds Gameplay, Graphics & Sound

The game's visual style is based on the H.G. Wells novel, with a colour palette that leans into the Victorian sci-fi aesthetic. The reels are set against a backdrop that evokes the Martian invasion, and the symbols include characters and elements from the story. The animation and sound are designed to build with multiple wins, according to the game description on Casino City.

The game includes licensed music and sound effects. Players who prefer modern, high-definition visuals may find the presentation dated, but the atmosphere reflects the era in which the game was released.

The War of the Worlds Slot Features

The main features of The War of the Worlds are expanding wilds, scatter symbols and a multi-scene bonus round. The wild symbol expands to cover the whole reel, which can create multiple winning combinations across the 100 paylines. The scatter symbol triggers the bonus round, where you command cannons to destroy Martian invaders. The game also includes autoplay for continuous spinning.

The available information does not confirm whether the game includes free spins or multiplier symbols. The expanding wild is the primary base-game feature, and the scatter symbol is used to trigger the bonus. The bonus round is a separate interactive sequence rather than a standard free-spins feature.

Bonus Features: Wilds, Multipliers, and Free Spins

Expanding Wilds

The wild symbol substitutes for other symbols to help complete winning paylines. When it lands, it expands to fill the entire reel. This is the main feature in the base game.

Scatter Symbols

Scatter symbols trigger the bonus round. They can appear anywhere on the reels, and the number required to trigger the feature is shown in the paytable. Scatters do not need to land on a payline.

Bonus Round

The bonus round is a multi-scene sequence where you command cannons to destroy Martian invaders. It is not a free-spins feature; it is an interactive bonus that plays out across several screens. The available information does not specify whether your choices affect the overall return.

Multipliers and Free Spins

The available information does not confirm the presence of multiplier symbols or free spins in The War of the Worlds. The bonus round is the only special feature beyond the expanding wild and scatter.

Other The War of the Worlds Features

Beyond the core features, The War of the Worlds includes autoplay, which allows you to set a number of automatic spins. The game also has a paytable that shows the value of each symbol and the number of scatters needed to trigger the bonus. The available information does not mention a gamble feature or progressive jackpot.
