Invading Vegas Slot Overview
Invading Vegas is a 5x4 video slot from Play'n GO built around a simple hook, aliens wrecking the Las Vegas Strip while walking wilds and respins try to lift the action. I get 20 paylines here, a medium volatility profile, a 96.20% RTP on the default version, and a top prize of 1000x the stake. What stands out here is the visual presentation, which leans into camp sci-fi comedy more than menace.
Compared to the studio's previous work, the setup feels familiar. The design choice to centre the game on a lock-and-respin sequence and then mirror that idea in free spins makes the slot easy to read, but not especially adventurous. I think it is best suited to players who want recognisable mechanics, a lighter Vegas theme, and a ceiling that is modest by modern standards.
Invading Vegas Slot Information
Across the 20 paylines, wins pay from left to right and must start on reel 1. The low symbols are coloured casino chips, each worth 1x the bet for five of a kind, while the premium cast includes an old lady, a journalist, a showgirl, an oil billionaire, and a fake Elvis. Five premium symbols pay from 2x up to 12.5x the stake, with fake Elvis at the top.
Alien wilds match the top premium at 12.5x for five of a kind and substitute for all regular symbols. Scatters are UFOs marked for bonus play, and they pay 0.1x, 2x, or 12.5x the bet for 3, 4, or 5 anywhere. Stacked high-paying symbols are also part of the paytable logic, and their positioning matters a lot once the bonus round starts.

Triggers free spins when 3 or more land anywhere, and also pays a scatter prize.
Invading Vegas Slot Features
First, the Lock On Respin triggers when fully stacked matching symbols land on reels 1 and 2 without creating a win. Those reels stay fixed while reel 3 respins. If a stacked wild lands there, it turns into a Walking Wild and moves one reel at a time to the right with each respin until it reaches reel 5. At that point, an extra respin follows.
Next, 3 or more scatters trigger 12 Free Spins. The key change is that the grid flips, so the former reels 4 and 5 become the first two reels. That improves the placement of stacked premium symbols, and the walking wild now travels left instead of right. Three scatters can add 12 more spins, up to 120 in total. One source says free spins may also land during the respin, while another says scatters cannot appear during the walking wild sequence, so that part is not entirely clear.
Bonus Buy Options
Triggers when fully stacked matching symbols land on reels 1 and 2 without forming a win. Those reels lock and reel 3 respins, with the chance to land a stacked wild that becomes a walking wild.
A stacked wild on reel 3 during the respin turns into a walking wild and moves one reel at a time. In the base game it walks right, and in free spins it walks left.
Triggered by 3 or more UFO scatters and starts with 12 free spins. The reel order flips, stacked premium symbols move to reels 1 and 2, and 3 scatters can re-trigger 12 more spins up to 120 total.
Review Summary
Visually, I think Invading Vegas is stronger than its maths model. The alien invasion theme has a cartoon edge, the character art is lively, and the changing background during the bonus round gives the game some theatrical movement. What stands out here is how much effort went into the setting, from the damaged ship to the recognisable Vegas landmarks around the reels.
Less convincing is the feature depth. The base game can drag a bit, and the 1000x maximum win leaves limited room for a standout moment, even if the walking wild can create satisfying sequences. The design choice to rely on stacked symbols, a respin, and a mirrored free spins upgrade keeps everything accessible, but players looking for fresher mechanics may find it too close to older ideas.
