Chance Machine 20 Overview

Chance Machine 20 is a classic-style slot from Endorphina running on a 5x3 grid with 20 fixed paylines. It went live in September 2020 and leans hard into a luxury diamond and jewellery theme. Deep red background, golden frames, sparkly gems for the low-pay card suit symbols. Proper old-school stuff.

Honestly, my first impression was that it looks nice but feels quite bare under the hood. No free spins round, no bonus buy, just Expanding Wilds and a Risk Game. If you want something simple for a lazy evening spin, it fits that brief. Just do not expect fireworks.

Symbols and Paytable

Seven is the top-paying regular symbol here, landing 150x your base bet for five of a kind. Below that you have got golden bells and then the gem-styled card suits for the lower end. Not a massive range but fair enough for a low volatility game.

Scatter-wise, there are two separate ones. Gold Stars appear on all reels and five of them pay 100x your bet. White Stars only show up on reels 1, 3 and 5; three of those give you 20x. Both pay regardless of position on the reels, which is decent. The Crown acts as the Wild and only lands on reels 2, 3 and 4. When it can help complete a win, it expands to fill the whole reel.

Expanding Wilds and Risk Game

Expanding Wilds are the main event. When a Crown lands on reels 2, 3 or 4 and contributes to a winning combo, it stretches to cover every row on that reel. Get two or three crowns expanding at once and you can hit multiple paylines in a single spin. That is where the bigger wins come from.

After any win you can trigger the Risk Game. Pick one of four face-down cards; beat the dealer and your win doubles. You can repeat this up to ten times, so theoretically you could multiply a win by 1024x. Risky, obviously. I have never got past about four rounds myself before the dealer pulled a higher card.

No free spins feature, no pick-and-click bonus, no multiplier trails. For some players that will be a dealbreaker. Personally I think it keeps things straightforward, but the lack of variety does mean sessions can drag a bit after a while.

Bonus Buy Options

Risk Game
After any win, pick one of four face-down cards. If your card beats the dealer, the win doubles. Repeat up to 10 times.

RTP, Volatility and Max Win

RTP sits at 96.01%, which is bang average. Volatility is low, so you get fairly regular small hits rather than long dry spells followed by big payouts. Max win is 1300x your stake. Not massive by modern standards but reasonable for a low-volatility classic slot.

Bet range runs from 0.20 up to 200 per spin. Casual players can keep stakes tiny and still get a good session out of it. The low volatility means your bankroll stretches further, which I appreciate for a relaxed evening session with a cuppa.

Ryan Cole’s Verdict

Final Verdict

Chance Machine 20 is about as straightforward as slots get. Low volatility, clean visuals, no complicated bonus rounds to learn. If you fancy a no-fuss classic slot for winding down, it does the job. The expanding wilds on the middle reels give you something to root for on each spin.

Where it falls short is variety. No free spins, no bonus buy, and the 1300x max win cap means you are never going to see a life-changing payout. I would not pick it for an exciting session, but for a quiet spin where you just want steady action and a pretty screen, it is a decent enough choice, mate.
