Space Invaders

Space Invaders is Inspired Gaming's slot adaptation of one of the most influential arcade games ever made, the classic 1978 shoot-'em-up that had players weaving a ship left and right while blasting descending waves of alien invaders. It's a theme so recognisable that it barely needs introducing, and given how popular retro-arcade slots have become, it was only a matter of time before it received the full reel treatment.

Rather than replicating the original's stark black-and-white visuals exactly, Inspired Gaming has brightened things up considerably, delivering an 8-bit-styled game that feels more like a 90s reimagining than a period-accurate recreation of the late-70s original. The sound design pulls its weight too, with rhythmic chiptune music and satisfying laser-gun bleeps doing a lot of the work to sell the arcade fantasy, even without the smell of a darkened games hall to go with it.

Structurally, Space Invaders runs on a 5-reel grid with 20 fixed paylines, evaluated left to right across adjacent reels. There are 8 regular pay symbols split across two tiers: four blocky invader designs make up the lower-value end, paying 2.5x to 5x the stake for five of a kind, while three space-themed pictures and the game's own logo occupy the premium tier, worth 10x to 25x the bet for a full line. Wild symbols can appear naturally on the reels or get added via the game's features, and once in play they substitute for every symbol except the scatter.

On the numbers, Space Invaders carries a 95% RTP with medium-high volatility, a fairly typical pairing for a retro-styled slot built to deliver a mix of regular smaller wins and the occasional bigger swing. The maximum win is set at 1,250x the stake, which converts to a $250,000 cash prize at the top stake level, and betting runs from 20p up to £/€200 per spin, giving a wide enough range to suit different bankrolls. It's worth noting that 95% sits a touch below the market's typical 96% benchmark, so it's not the most generous return you'll find, though it remains within a normal range for the genre.

The retro-arcade slot category has become genuinely crowded, but Space Invaders has an edge that pure pastiche games can't claim: it's built on the real thing, a title that shaped an entire era of gaming. That authenticity, paired with a competent if not spectacular betting structure, makes it worth a look for anyone with a soft spot for classic arcade shooters.
