Chance Machine 20 is one of the classic slot machines that you will find at Endorphina casinos. Itβs a 5-reel slot machine that offers a classic design, using a bit of Irish luck inside as well. The setup gives us 5×3 reels to spin each round, with the 20 active lines allowing you to form winning combinations.
Every slot machine must be developed by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific software provider, so they narrow down their selection by preferred brand.
A slot machine with low volatility. Wins occur frequently, but are usually small. The game has a smoother course without large fluctuations, suitable for players who do not like risk and work with a smaller budget. More about volatility here.
Slot theme and symbols
When it comes to the look of Chance Machine 20, you shouldnβt expect anything out of the ordinary. A typical online slot with a classic theme usually has a classic design as well. This means that it copies the look of older games, and so the design quality doesnβt match what you will find in much more modern Endorphina slots. Theyβre certainly capable of delivering great graphics; theyβve proven it with other games, but the theme of Chance Machine 20 requires a different look. You get 8 regular symbols, plus 3 feature symbols.
Chance Machine 20 theme and symbols
One advantage that Chance Machine 20 has over other slots is the fact that its volatility is Low. The prizes it can pay as a result will be lower than youβd expect from todayβs games, but at 1,250x the stake, Iβd still say that itβs worth pursuing. Add to this the 96.01% RTP thatβs expected over the gameβs entire life, as it tells you that itβs fair (pays back about as much as any other slot in the long run).

WILD symbol
One of the few special feature symbols that you will find in Chance Machine 20, the wild symbol has the image of the Crown, and it will land only on reels 2-4 (middle three reels). When it lands there, it substitutes for other symbols, and if this gets you more wins, it will expand to take over the entire reel theyβre on.
Yellow Star Scatter symbol
One of two scatter symbols available in this game, the Yellow Star can appear on all reels. Its only role is to pay when it lands on 3 to 5 reels, its prize being worth 3x to 100x the stake. You donβt get any other feature from it, just that prize.
White Star Scatter symbol
You can also get White Star scatters to land, but those are available only on reels 1, 3, and 5. If you can get all three to appear at the same time, regardless of the exact positions they occupy on those reels, you get paid 20x the roundβs stake.
Risk Game (Gamble)
You will get the option to trigger a Risk Game at the end of winning spins. This allows you to gamble your winnings for that round, trying to double them (if you win), though you can also lose them.

Our rating of the game
Chance Machine 20
If youβre interested in an experience as simple as possible, with low volatility and a fair RTP, then Chance Machine 20 might be the right slot for you. Itβs not going to give you the same modern graphics that other slots deliver, but you get very simple gameplay with few features to worry about, and it pays up to 1,250x the roundβs stake, if youβre lucky. Itβs great for a fan of the classics, or for someone who doesnβt want a lot of features or high risk.
