Angels & Demons is a slots game from the team at Simpleplay. With a generous return to player (RTP) of 96% and some fantastic special features and bonuses, it's... definitely worth checking out. The game's theme is heaven and hell (perhaps unsurprisingly, given the title) and there are 30 paylines to keep things exciting. Simpleplay might not be as big a name as the likes of NetEnt, Microgaming or Playtech, but you'll probably recognise some of the brand's titles if you've spent time playing slots in online casinos. Fortune Cat and Prosperity Tree are probably two of the better known.

Angels & Demons Game Theme
The theme of heaven and hell is surprisingly original in the slots world - you might expect many more providers would boast games in this category, but they're actually few and far between. The angels and demons in question in this game are actually sexy female characters, while the other symbols are a combination of traditional playing card symbols and picture symbols related to the game's theme. This is a well-designed game, and if you like the look of this, you should check out other SimplePlay Slot Machines.
Angels & Demons Graphics & Soundtrack
The graphics are excellent, and this looks like a high-quality slots game from the moment you launch it. Despite the game's appearance, the soundtrack is nothing to write home about. When you spin the reels, you'll hear a generic spinning sound effect and nothing more. You do get a brief fanfare of music if you land a sizeable win, but still nothing special. The soundtrack is actually at odds with the game's high-end graphics and innovative gameplay, but this shouldn't detract from the experience too much for most people.

How to Play Angels & Demons
As this is a variable payline slot, you'll have a few adjustments to make here to get your perfect bet lined up. The maximum number of paylines you can bet on is 30. Remember that betting on the maximum number of lines will give you the best chance of hitting a winning combo, but be careful to never bet more than you can afford to lose if you're playing with real money. You can change the number of paylines by using the plus and minus buttons on either side of the line display. You can cycle through the paylines in increments of one, meaning you can tailor your bet completely. You'll also need to choose the coin size you want to play with. There is a coin display alongside the line display - click on the coin display and a pop-up menu will show the available coin sizes. The final thing to do before hitting spin is to select how many coins you want to bet on each line. For example, if you choose a coin size of two and bet on all 30 lines, and choose to bet one coin on each line, you will be betting 60 coins. If you choose to bet two coins on each line, your total bet will be 1.20. Play around with the settings until you're happy with the amount displayed in the total bet window.
Once you're happy, hit the spin button and watch the reels leap into action.
Bonus Features of Angels & Demons
The base game has a wild symbol (the heart) that appears on reels 2, 3 and 4 and substitutes for all other symbols except for the scatter. Speaking of the scatter, this can appear on any reel, and when three or more appear, the free bonus games round is triggered.
The free games are awarded automatically when you land three or more scatter symbols in the base game. The free games can be highly lucrative if you get lucky, and they feature a special wild symbol on reel 3. The normal wilds appear on reels 2 and 4, as in the base game, but the special reel 3 wild comes with an extra treat - a multiplier. The multiplier starts off as 2x but increases by 1x with every five spins. When you trigger the free spins feature, you'll be invited to choose either angel spins or demon spins. Your choice will determine which special wild you get, although they differ only in colour and both behave in the same way. You start off with unlimited free spins (in reality, up to a maximum of 80 free spins!) and the free spins session ends whenever the un-chosen special wild lands on reel 3.
Payout & Volatility of Angels & Demons
This game has a return to player (RTP) of 96%. Generally speaking, most people who regularly play online slots look for an RTP of 95-96% as a minimum, so this one would meet with their seal of approval! The RTP is a rough indication of how much you can expect to win from a game. If you bet 100 coins on this slot, you should, in theory, expect to win 96 coins back. It's worth bearing in mind, however, that the tests that are run to calculate these things are complex and long-winded, so it's highly unlikely you would end up with exactly 96 coins from your initial 100 if you attempted this in a real-life scenario! The volatility of this game is high, which means you should, broadly speaking, expect few wins but with the possibility of large wins occasionally.
