Aeterna is an online slot like no other, boasting a revolutionary Orbital Reactor™ engine never before seen. Fittingly for a futuristic game set in deep space, the reels spin in orbit as we look to match game symbols around the edge of the orbits – on the Orbital Paypath. Effectively Aeterna is a three reel slot but the three reels spin around each other rather than side by side, like a rotating wheel space station out of a sci-fi film. The winning game symbols highlight and disappear, allowing new symbols to cascade in their place. A +1 win multiplier is awarded for each consecutive winning spin, which doubles during the Free Spins bonus game. The Twin Win Booster™ feature can also activate at any point during the base game.

Pros & Cons

  • Innovative Orbital Reactor™ Engine pay system.
  • Incremental win multiplier for every winning cascade.
  • Up to 30 free spins awarded.
  • Only adjacent symbols around the edge of the orbit award payouts.
  • The bonus game is very similar to the base game.
  • No Wild symbols.

How to Play

To access the game’s autoplay features and select your bet level press the three lines above the spin button and use the slider to select your bet. You also have the option to autoplay up to 100 spins. To spin manually press the spin button and watch as the three reels spin inside each other, powered by the Orbital Engine™. The Orbital Engine sets Aeterna apart from other space themed slots like NetEnt’s Starburst or Thunderkick’s Arcader, as you have to match three or more symbols around the outside edge of the orbit along the Orbital Paypath. Land three symbols to score a win according to the paytable, and with each win an incremental +1 multiplier is awarded. The circle around the reels fills up with each win, charging along with the multipliers up to a maximum of x20 during the base game and x40 during the free spins feature.

Symbols

All the game symbols are various futuristic shapes of different orientation and colours. The game’s lowest paying symbol is a turquoise pyramid that awards between x0.4 – x10 your stake for landing between 3-6 around the orbit. The highest paying symbol is a bright green cuboid that awards payouts of x12 – x1,000 for 3-6 around the Orbital Paypath. There are no Wilds in Aeterna but the blue A Scatter triggers the Free Spins bonus feature when four or more land around the Orbital Paypath.

Bonuses

Aeterna features an in-game bonus as well as a dedicated Free Spins feature that is triggered by landing A Scatters. Just like the base game the bonus features are truly innovative and revolutionary, and are similar in that way to Lady Earth from Crazy Tooth Studios, another online slot game that reinvents the standard way of doing things to deliver a unique gaming experience.

Bonus Name Bonus Explanation
Free Spins

Land four or more A symbol Scatters around the Orbital Paypath to launch the feature. The Orbital Paypath becomes a series of free spins, between 5-30. The game continues as during the base game, but during the Free Spins feature the win multiplier is doubled, starting from x2 and increasing in increments of 2 all the way up to x40.

Twin Win Booster Bonus

Land two sets of three matching symbols around the edge of the Orbital Paypath to trigger the Twin Win Booster™ Bonus. A symbol then appears in the centre of the Orbital Paypath, which transforms all symbols to match. The bonus then boosts the six symbol win x6!
