Play Run Amuck for Free

If you enjoy cartoon-style games with plenty of humor, then this is one you won’t want to miss. Everything from the manic microbes to the cheerful soundtrack adds to the fun. You have a top-down view of a 7x7 grid surrounded by strange mechanisms in the laboratory of some mad scientist.

Four colorful beakers and bottles feature on the grid, plus green, orange, purple, and blue bacteria. The lower paying symbols can appear as singles, doubles, or triples in one spot, while the bug-eyed bugs can take on baby forms of themselves in a dish or as all-singing, all-dancing grown-up versions. Call them bacteria, germs, or microbes; they will certainly raise a smile when you see them on the Run Amuck slot machine grid.

It comes from US-based High 5 Games. This long-establish developer is behind famous titles such as Secrets of the Forest and the Da Vinci Diamonds series.

You can place bets from a low limit of 0.20 to a generous 400.00 on each spin. We say ‘spin’ but what actually happens is that symbols grow from the middle of the 49 symbol positions to cover the whole grid in a split second. The Run Amuck online slot is a cluster pays game, and you need four or more examples of the same symbol grouped together for a win.

You play with 20 coins, and win coin multipliers. Our paylines table shows you how much the minimum of four and maximum of 48 matched symbol pay out –

The reels can spin in Autoplay mode for up to 100 games, but be sure to select a loss limit, as this is a high volatility game that can make you wait a while for a winning combination. The prizes tend to be relatively big to make up for it. The average payback percentage of 96% is reasonable enough, but nothing special.

The Run Amuck slot machine uses what High 5 Games call a Racking up Riches feature. Any cluster of two or three test tubes or baby bacteria will collapse into themselves. This results in two or three matched tubes or babies in a single position.

Four matched symbols appear as four test tubes, or the adult bacteria, which dance around in comical style. Once all symbols have collapsed as far as they can, all non-winning symbols vanish, and new ones grow in their places.

If the new arrivals can collapse into four tubes or grown-up bacteria, the process repeats until the grid can create no new combinations. It’s at this point that all combinations get evaluated, and you get paid any prizes.

A brightly lit piece of the lab equipment is a special bonus symbol of the Run Amuck online slot. It only appears in the corner positions, and any three or four examples award eight or 30 free games. Before each free spin, between one and three groups of test tubes or adult microbes appear in random places, to get clusters off to a head start.

Cyrus the Virus is a slot from Yggdrasil that features a virtual plague of colorful cartoon bugs across five reels and five lines. The purple Cyrus is an angry-looking wild symbol that expands over any reel before triggering a respin of the others.

More cartoon microbes appear in the Germinator slot machine by Microgaming. It plays out on a 6x6 grid with 12 lines and has a cascading reels system. Bonus pill symbols remove whole lines of germs for bigger cascades.

The fun cartoon antics of the germs give the Run Amuck slot machine great visual appeal. It’s a fast-paced slot, with collapsing clusters occurring left, right and center, and keeping up with the action can be difficult. It’s perhaps best to just sit back and watch the winnings build up from this exciting Racking up Riches mechanism.

Once symbols start to cascade into each other, it becomes easier to see further collapses in the same sequence. We found that having a head start in the free games feature can turn almost any spin into a big winner.
