Features and benefits

Wilds

The wild symbol appears throughout the base game and bonus rounds. It will substitute for any regular symbol, helping you form wins across adjacent reels from left to right.

Reel modifiers

During the base game, there’s a random chance for a UFO to appear above the reels on any spin. The cannon appears and attempts to shoot it down. If it’s successful, one of five reel modifiers will be awarded:

• Wild cannon – The cannon shoots at the three central reels, adding wild positions at random for the next spin.

• Monster wild – Any wilds that land on the next spin expand to cover the full reel.

• 5 of a kind – Guarantees at least one five-of-a-kind win on the next spin.

• Mega reel – Adds a 3x3 mega symbol to the reels for the next spin.

• Bonus boost – Extra bonus scatter symbols are added to the reels for the next spin.

In addition, a special reel modifier can be applied on a losing spin. At the end of a losing spin, there’s a chance for the following modifiers to trigger:

• UFO only – A UFO will fly over the reels and shine a beam onto a random symbol, causing it to grow to super-size.

• Cannon only – The cannon appears below the reels, shooting random alien symbols, causing a cascade win.

• Lock n spin invasion – At the end of the spin, all symbols of the same type lock into place. The reels then spin, with any new symbols of the same type also locking into place.

Scatters

The golden coin is a scatter symbol, and landing three or more anywhere on the reels will trigger the bonus wheel.

Bonus games

If you’re lucky enough to land three scatters, you’ll get to spin the wheel to win one of the six bonus games. These are:

• Shoot out – Press the fire button to shoot at invaders and UFOs. If you completely destroy one type of invader, you’ll win the multiplier prize.

• UFO climber – Pick a UFO and climb a trail of increasing multipliers. If you reach the end, you’ll get to play the Space Invaders bonus game.

• Wild cannon free spins – A cannon appears to add sticky wilds, which remain on the reels for the full bonus round.

• Monster wild free spins – Any wild that lands will expand to cover the full reel.

• Mega reel free spins – The central reels contain a mega 3x3 symbol during the bonus.

• Space Invaders game – Shoot invaders and UFOs to accumulate wins. If you destroy all invaders, you’ll earn an extra prize.

At the end of the bonus round, you have a chance to be offered the choice of three coins. Pick one to reveal a random prize:

• Bonus terminates, with any accumulated prize awarded.

• Bonus continues, with extra spins awarded for any free spins bonus.

• Space Invaders bonus is awarded, with any winnings added to your current winnings.

Gameplay and winning potential

Space Invaders online slot has a classic 5x3 layout, and you can land wins by matching symbols on adjacent reels from left to right. The maximum win while you enjoy Space Invaders gameplay is 1,250x your bet.

RTP and volatility

The theoretical average return to player rate (RTP) for this game is 95%. This represents the average return over an extended period of time, but for normal playing sessions you could see higher or lower returns based on your luck.

When you play Space Invaders slot, the volatility is high, which is apparent with the large volume of dead spins. While the payouts can potentially be larger on average, wins are less frequent.

My verdict

I had a lot of fun playing Space Invaders, and although I wasn’t lucky enough to hit some big wins, I did get to enjoy some of the bonus modifiers and Space Invaders free spins. As a fan of the classic arcade game, I really enjoyed the theme, with the art and sound creating a feeling of nostalgia while playing. One aspect I wasn’t too keen on was the high volatility, which left me with a lot of dead spins. Still, the Space Invaders bonus features I got to experience were all great fun, and there’s lots for all players to enjoy.
