Step into a post-apocalyptic world where you have to fight unknown hostile entities to survive. Dark Echo is an online slot game by Bet365 Games with a retro vibe. It definitely includes elements inspired by the popular TV series Stranger Things. The graphics found here are cartoon-like. You can find original icons, blue reels, and a massive building in the background.

Dark Echo is played on 5 reels and has 20 paylines. The list of basic symbols present in the base game includes a green bicycle, a cap, a retro sneaker, an inhaler, a paper bag, a watch, a Walkman, a walkie talkie, a map, and a skateboard. There's a different payout table for the bonus game and this paytable includes monsters. The shiny wild sign is a wild icon that replaces missing basic symbols. Get three suit Scatter icons on the first, third, and fifth reel to activate 7 Free Spins where every win is multiplied by three. This mode features sticky wilds too.

With three vine scatter icons on the middle three reels, you will activate Vine Pick Me and Free Spins. This means that you will receive 10 free spins with a x3 multiplier for the wins. The number of free spins and the value of win multipliers can increase thanks to the Vine Pick Me mini-game played before the round of free spins starts.
