Look to the skies, UFOs are invading… Las Vegas? That’s right, Play’n GO pairs the ever-popular City of Sin with little green men in Invading Vegas, bringing about a rather unique mix as far as slots are concerned. A Lock On Respin feature brings a chance of solid wins if the first 2 reels hold the same stacked symbols, while landing at least 3 flying saucer scatters awards you with free spins. So join us in our definitive Invading Vegas review as we tell all about this interstellar game!

Invading Vegas RTP and Wagering

Invading Vegas - RTP and Wagering

Invading Vegas features the standard slot setup with 5 reels, 3 rows, and a total of 20 paylines. You can actually adjust the number of paylines you want to play using the controls in the bottom, together with the number of coins you want to bet and the value of each coin. If you’re confused as to the total value of your bet, don’t be - you can see this at all times in the panel in the lower right–hand corner, next to the number of paylines. 

The game does feature one of our bugbears of Play’n GO slots, which is operator-adjustable RTP. The default setting is 96.2%, but you can find versions with an RTP as low as 94.2, 91.2, 87.2, or even 84.2. As such, always check the “About” section of the slot game before committing the cash. The volatility is of a comfortable Medium level that should prove just right for most players, while the max win looks impressive at 100,000 coins. However, do the math and turns out this is worth all of 1,000x the stake.

Invading Vegas Symbols and Audio & Video Design

Play’n Go brings a bold painted style in Invading Vegas, bringing us a world inhabited by colourful characters. This is Las Vegas after all, as you can see in the background. It features - where else - the Vegas Strip, where a UFO has crashed among the famous casinos. It’s night time, and the atmosphere is rich in neon and lights, not to mention potential alien invasion! 

The reels hold 9 different paying symbols, which are divided between 5 high and 4 low pays. The high-paying symbols are Vegas characters, with Elvis, an oilman, a showgirl, a journalist, and an old lady filling the ranks. The low pays meanwhile consist of casino chips in red, green, blue, and purple. All symbols are in the same painted style, and feature animations that play out whenever they make part of a win. The alien wild can appear in reel-filling form and can substitute for all symbols except the UFO scatter.

Invading Vegas Bonus Features

Invading Vegas has three bonus features - the Lock On Respin, Walking Wild, and Free Spins. Let’s take a look at each of these here. 

Lock On Respin

Land stacks of the same symbol on reels 1 and 2 with no win for a Lock On Respin. This is a free respin of the third reel that brings an extra chance for a win. This respin cannot be retriggered.

Walking Wild

If you land a stack of 3 wilds on the middle reel during the Lock On Respin these will turn into a Walking Wild. This means a series of respin where the stacked wild moves by 1 reel to the right with each respin. Once the Walking Wild walks off the reels you’ll get an additional respin before you get back to the regular paid spins.

Free Spins

Landing 3 or more UFO scatters anywhere on the reels awards you with 12 free spins. During these you can land a Walking Wild on the middle reel, only in this case the wild will move to the left on each respin until it walks off the reels. The Lock On Respin is also active during this round, and Play’n GO promises there are more chances to land stacks of high-paying symbols on reels 1 and 2.

Invading Vegas Final Thoughts

Invading Vegas is a charming, if perhaps old fashioned, video slot with an excellent art style reminiscent of the B-movies of the 1950s. That said the Lock On Respin feature does bring some excitement, especially whenever it leads to a Walking Wild. That said the maximum wild is a tad low at 1,000x, while the variable RTP is always concerning. 96.2% is the standard figure, but we’ve seen it get as low as 84.2%, which is not great to say the least. As such this is a fun slot, but always check its About section carefully before committing the cash.
