This article is not about what is good and what is bad in online slots. It is about slot machines with the theme of good and bad. This pairing of opposites makes the slot machine more interesting both in appeal and in gaming features. The slot games reviewed here are really worth checking out.

The software provider Realtime Gaming released a slot game with a Christmas theme titled Naughty or Nice. In a slightly risqué twist, Naughty and Nice are Santa’s female helpers. Nice, being nice wears a one-piece provocative dress, whereas Naughty is bolder and dons a two-piece outfit. Both are wild symbols. The other symbols on the reels of interest are Santa Claus, an irate Mrs. Santa brandishing a rolling pin and a reindeer with a bra hanging from its antlers. In the free spins round you choose Naughty or Nice to be the Bonus substitute, which will double the payouts during the free spins apart from offering other benefits. The Naughty or Nice slot machine also has a progressive jackpot, which is hit when five Nice symbols or five Naughty symbols appear on an enabled payline.

We all have been told that angels are good and the devil is evil. But the devil has more temptations to offer. The software provider Playtech offers a slot game with this concept at its online casinos. It is titled Angel or Devil. Both the angel and the devil are wild symbols, but the devil tempts you with something more. It offers a bigger jackpot payout and also acts as a 2x multiplier. The devil tempts even more in the bonus game. If you choose the free spins closer to heaven you will get a steady stream of small wins, but if you choose them closer to hell you will get a few naughty wins that are really huge.

A similar feature is present in the 3D slot machine Good Girl Bad Girl from BetSoft. If you choose the Good Girl mode you will get frequent but smaller payouts. Wins pay out from left to right in the conventional manner. In the Bad Girl mode the wins are less frequent, but they have the potential to be higher. Going against convention the wins pay out from right to left. One advantage that this slot machine offers is that you can play in both modes for twice the standard wager. Wins will pay from both left to right and right to left.
