Beach Invaders Slot Review: Locked Wild Progress and Teleports

Beach Invaders links ordinary spins to a progress bar: pink plasma patches attach to eligible symbols, and milestones determine how long future Expanding Wilds lock in place. In Free Spins, that bar disappears and the Wilds follow a different movement rule, teleporting left while shrinking and gaining a multiplier. The two modes therefore use Wild persistence in opposite ways—fixed for a limited number of base-game spins, then mobile and increasingly valuable during the ten-spin bonus.

Patches prepare the base-game Wilds

The base game uses five reels by four rows, line wins and up to 30 lines listed. Expanding Wilds land as flip-flop aliens, cover their entire reel and substitute for paying symbols but not Free Spins Scatters. They lock for one to four spins according to the progress bar. Pink plasma patches can attach to symbols other than Wilds and Free Spins Scatters; up to 20 patches may be collected in one spin. One milestone is reached after 30 patches. The bar has four milestones, each representing the number of spins an Expanding Wild locks to the reels when it appears. When full, the bar resets and additional patches fill the next progress.

If a new Wild lands where an existing Expanding Wild with a multiplier already sits, it re-expands across the reel and takes the current multiplier as its starting point. This is a specific carryover interaction: the new arrival does not begin from an unrelated value if it overlaps an already multiplied Wild. The source does not enumerate the patch total for every milestone or state the exact order of overlap resolution, so the recorded one-milestone/30-patch rule is the only threshold used here. In ordinary play, a patch on an eligible symbol contributes toward duration rather than directly paying a prize.

Free Spins make Wilds travel and grow

Three Free Spins Scatters award ten rounds, and the progress bar disappears. Wilds still expand to cover the reel where they appear, but each comes with a multiplier. On every spin, a Wild teleports one reel to the left and shrinks by one symbol in height while its multiplier increases by ×1. It disappears when it becomes one symbol high or reaches the leftmost reel. Values range from ×1 to ×5, and Wild multipliers participating together in a win add together. This is a finite journey: reaching either stated disappearance condition ends that Wild’s path, even if the bonus itself continues.

The bonus thus exchanges the base game’s lock duration for motion and multiplier growth. A Wild that starts larger has more height reductions before reaching one symbol, while a Wild that reaches the left edge disappears regardless of remaining height. Multipliers can increase during the journey, and several Wilds can add their values when they share a winning combination. The source says the progress bar disappears, so the base-game patch stock should not be treated as continuing into the feature. This creates a clean mode boundary: patch collection determines lock length before the trigger, while teleport steps govern Wild value and lifespan after it.

Reference figures

The official record lists RTP 96.09%, volatility 23.26 and maximum payout 20,847× bet for the exact title. Operator settings may differ, and no maximum-win probability is given. The source documents up to 20 patches per spin and four milestones but only names the first milestone threshold as 30 patches; it does not state all later thresholds. Those omissions do not change the core transition from locked Wilds to moving multiplier Wilds, but they limit how precisely the base-game progression can be mapped.

Strengths and weak points

Strengths

The base and bonus modes give Expanding Wilds distinct jobs: patch progress controls lock duration, while Free Spins use leftward movement, shrinking height and rising multipliers.

Weaknesses

Only the first 30-patch milestone is quantified, and later thresholds are missing. The bonus Wild’s lifespan also depends on two separate stopping conditions that can end its path.

Our Editor’s View

Beach Invaders has a useful contrast between preparation and movement. Patches build the base-game duration of reel-wide Wilds, and the overlap rule lets a returning Wild inherit a current multiplier. Free Spins discard that progress bar and give Wilds a new lifecycle: move left, lose one symbol of height, gain ×1 and disappear at the edge or minimum height. The rule set is spatial and relatively concrete, so the change between modes is easy to explain. Its limitation is that the packet gives only one of four patch milestones and does not document all thresholds, leaving some of the base progression opaque. Players who enjoy watching Wilds change position and value should find the bonus distinctive; those wanting complete meter arithmetic may need fuller rules than this record contains.
