Graphics & Soundtrack

The lights can be off and it will still work because this is more of a cartoon game. Funny pictures plus interesting movements help maintain an easy flow in the game, with sounds not trying to be overtly scary. Furthermore, there are other great features such as bats flying on the screen and all playing card symbols represented by gravestones; which we found amusing.

Sin Reels RTP & Volatility

This online slot has a RTP of 96.77% which is above average, so it is a tempting game. However, play for free before playing with your own money on this game. The slots has been given a medium volatility rating of 3/5 by Promatic. However, every win you have will at least pay back the amount you have bet, unlike many other games in the genre so there are no losses to players at any point!

How to Play Sin Reels

Creating simple interfaces for their slots games is something Promatic are masters at. This means that even if you’re not much of a gamer, Sin Reels is here to deliver some scary thrills to you!

Your bet can be set by using the controls at the bottom left corner of your screen.

2 Find out the dynamic paytable for the game so that you know how much money you’d get from your current stake. You will see this if the far left of your console has a settings button and click on it.

Press the Spin button in the middle to start playing. If you want to play several games, click on Autoplay; it is located on the right side of spin. You can also find it in settings. Additionally, during Free Spins, if you win any amount, you have a chance to gamble it for double or nothing with just a second before that option disappears. It will be good if you keep your finger above the Spin button for this reason and then press it after landing this option

Access to the payline structures of the game is also given by 4 Settings. Game sounds can be switched off as well.

Bet Sizes & Paytable Wins

Start playing Sin Reels at the lowest price of 0.01 and increase it to 10.00 in every spin just like in an online slot machine. Whenever you land three, four or five icons on a pay line from left to right, you get cash prizes for that. They are paid out as multiples of your total bet in all wins.

10 = 1x, 2x, 8x

J = 1x, 2x, 10x

Q = 1x, 3x, 15x

K = 1x, 5x, 25x

A = 1x, 7x, 40x

Witch’s hat and potion = 2x, 8x, 80x

Black cat = 3x, 20x, 300x

Ghost = 5x, 35x, 500x

Witch = 10x, 80x, 1000x

For 3 or more Scatters of Death, the stake you made will be multiplied by four then you can activate bonus round.

Sin Reels Bonus Features & Free Spins

Promatic, however, refers to it as the Joker. Whether named bat or otherwise, it can take the place of any other symbols except for Death Scatter and Skull in this game. As such, each appearance on the reels could possibly lead to a winning combination.

If you like a free spins feature – and who doesn’t? – then you will have to get three or more of the Death Scatters in any position on the reels. They do not have to comply with the standard payline rules as Scatters.   3 Scatters = 10 Free Spins

4 Scatters = 15 Free Spins

5 Scatters = 20 Free Spins

The skull icon does not serve its purpose during the base game, but in the Free Spins bonus round, it will earn a 2x multiplier for any wins that happen next to it on the reels.

Many online slots games have an extra optional feature called Gamble that adds more risk to the game especially for those who likes it. In most cases the colours on a playing card are what is used in this gamble, but Promatic like to be different in their approach. Therefore when you opt to go for double or nothing gamble, you will end up in a wet and dark crypt with torches burning bright to light up the darkness. Four coffins are lined against one wall and you are supposed to choose one of them. If your chosen coffin contains a coin your win is doubled, but if it’s empty you lose.

In case you win less than $100, you may gamble it. However, this can be done for a maximum of ten times in a row. Nonetheless, one of such guesses can be made using half of the winning amount provided it exceeds $2.

Overall Review

Promatic free play slots are absolutely irresistible. Although the gameplay may appear too simple, the games themselves are always full of details. Sin Reels is such a good Halloween-themed slot that it’s so much fun to play at any time of year. With a very generous Free Spins bonus round and a random Multiplier feature, some decent cash payouts can be achieved. You’ll need to try it out in practice without real bets first before you start playing for money in this one-armed bandit.

Consequently, I need to state that the Sin Reels trademark is the property of Promatic. I wish to disclaim that this website is not affiliated with Promatic.
