Doubles Slot is a Yggdrasil’s release. It is basically a classic-themed slot machine, but there is a contemporary touch to it. As you load this video game, you will notice the graphics are top-notch, crystal-clear, yet unusually retro. The theme is a beautiful mix of the new and the old, and as you will shortly see, so is the gameplay. Read our review to see why Doubles is so special, and you’d instantly get the desire to play it for real money.

Retro but Gold

On the reels of Doubles online slot, you will find Diamonds, Red Sevens, and Golden Horseshoes for the highest paying symbols, as well as a Green Star, Cherries, Watermelons, Oranges, Lemons and Plums. This is what you would expect to see in most classic slots, right? But, you will notice that the symbols look like if made of crystal, like coming from another dimension and still looking really sophisticated. There is a landscape in the background but portrayed with the same style of graphics. You will also see the bonus symbol DD (double D) which will, later on, help you trigger the bonus round.

Seeing Doubles

Don’t be scared about your sight. Your site is great, you are seeing double. The Double D bonus symbol, if it appears 3, 4, or 5 times on the reels, will trigger Free Spins. For 3 DD symbols, you get 10 Free Spins, for 4 DD symbols you get 20 Free Spins, but for 5 bonus symbols you get up to 40 Free Spins! During the Free Spins, you will need to choose a symbol that will convert all single symbols to doubles! This is a feature that is similar to the one in NetEnt’s Flowers slot, where symbols appear double and pay as two separate symbols. You can retrigger the Free Spins with the same DD symbols and get the number of Spins depending on the number of DD symbols you land.

You should know that symbols pay from left to right in adjacent winning combos, except for the bonus symbol. The DD symbol pays scattered.

Doubles Your Wins

Doubles slot offers 243 ways to win and a coin value that goes from 0.01 credits up to 2 credits. The bet, however, ranges between 0.25 and 50 credits, which means you're playing with 25 coins per spin. Yggdrasil has set a straight average RTP for this insanely big win video game, 96%.
