The Orphan Organ Slot Game

Humanity hasn’t even gotten to the extent of unearthing what aliens look like, and here we (the iGaming world) are exploring how their carnivals happen, thanks to Shady Lady. But for once, you mustn’t be scared about an impending attack from extraterrestrials.

Instead, the Orphan Organ delves into the pitiful world of six enslaved alien orphans captured from their destroyed homeworlds. They are bound by shock collars attached to electric metal and wire cages, and forced to sing. However, their weak voices symbolise the cruelty delivered through electric voltage.

The characters alongside their meters flank the 5 by 5 gaming field. And, while you’re enjoying payouts arising from the orphans’ suffering, perhaps you should try to imagine the savage extent to which the alien species could go to get what they want.

Symbols and Payouts

Everything about this video slot may look normal at first until you open the paytable and study the payout mechanic. Instead of the usual paylines, ways, clusters, or scatter pays, you’ll be using a new Meter Pays technique.

It means every Orphan Organ symbol that lands accumulates into its corresponding meter. The meter pays out a fixed value (as indicated in the paytable) multiplied by its multiplier when you collect 8 or more identical symbols. Any more symbols past the collected 8 are carried over to the subsequent cascade.

The game includes six regular symbols derived from different characters, coloured distinctly: Blue, Green, Yellow, Orange, Red, and Purple. They pay 0.2x, 0.5x, 0.7x, 1x, 2x, and 5x the stake for 8 of the same, respectively.

All the winning and consumed symbols are destroyed before disappearing, while the remaining symbols fall. Then, new symbols drop in and complete the empty spaces for more potential wins. The cascades repeat as long as subsequent wins happen.

The Orphan Organ also has a wild symbol, which substitutes for all the regular symbols in winning combinations, increasing the symbol count on all meters by one.

Orphan Organ Slot Bonus Features

Every meter also has a level determinant of how many steps the multiplier increases per payout. The level starts at one and can be boosted from a special feature awarded by the Arilocks.

Airlocks

You open the Airlocks by landing the Airlock trigger symbol. Every opened Airlock in Orphan Organ awards one of the following possible features/prizes:

  • Multiplier Increase - adds a number between 1-16 to a random meter’s multiplier. Before the addition of the increase, it’s multiplied by the meter’s level.
  • Meter Level Increase - awards a multiplicative upgrade of a random meter’s level. The increase, which can be between 2 and 10, multiplies the picked meter’s level and current multiplier.
  • Wilds - each wild appearing either as a symbol on the grid or in airlocks increases the symbol count on all meters by one. Their effect on the meters ends once consumed in wins or when the Airlock closes.
  • Harmony Face Huggers - they attach to a random meter, and all meters with a Face Hugger are linked. Whenever a meter is full and pays, all the linked meters will also pay out.

How to Win at Orphan Organ Slot

The primary unique aspect of this 5-reel, 5-row game is its payout process. As mentioned, this video slot employs a distinct Meter Pays system. It awards a win when you collect 8+ identical symbols, which fills the corresponding meter.

Orphan Organ meter pays

Then, the meter pays out the displayed paytable value multiplied by the current multiplier. A tumble feature starts after a win, removing all the winning and consumed symbols to make room for new ones, potentially triggering additional wins.

The Orphan Organ bets range from €0.10 to €50, making it ideal for low- and high-rollers.

Press the spin button or spacebar key to start a single round. Otherwise, use the Autoplay feature to preselect a desired number of auto-spins. Meanwhile, the Quickspin function reduces the total spin time.

Orphan Organ Slot RTP & Volatility

Depending on the casino you’re playing from, you’ll be exposed to a 92.14%, 94.15%, or 96.17% RTP. Then, the slot has high volatility and a maximum win of 20,000 times the stake!

The Concluding Thoughts

I can confidently conclude that there’s no stopping Shady Lady, even though the newbie company has only created five online slots so far. That’s because, unlike other game developers, this new studio is focused on offering unique value to gambling enthusiasts, thereby building an indestructible brand identity.

Every release from the young studio, including Orphan Organ, has been unpredictable, and there’s no guessing what the next creation will be.

Anyway, back to this game, it’s inspired by a provocative theme, where six alien figures are enslaved and forced to produce music. As such, their voices don’t evoke excitement but despair from constant cruelty, specifically electric volts delivered through their collars.

In short, it’s a disturbing scene, which may not suit every player. However, the chance to win up to 20,000 times the bet arises from their anguish. Perhaps the massive winning potential, combined with the unique Meter Pays system, may appeal to some. Furthermore, the gameplay has multiple features to boost your winning chances.

Myself, I didn’t mind the theme as it was well-completed and original. And if you’re in the market for something unusual, you should be at the right place. Just ensure you try the free demo to acquaint yourself, especially with the payout process, before committing your dough!
