Orbitfall: Slot Overview
While it wasn’t the first-ever video game, Space Invaders is often credited as the first shoot ’em up and one of the earliest games to introduce endless gameplay, having no final level. Released in Japan in 1978, Space Invaders became a defining moment for the arcade era, tasking players with defending against waves of descending alien invaders using a horizontal laser cannon. While its mechanics may seem archaic by today’s standards, its influence on the gaming industry is undeniable—something that can be felt in ELK Studios’ online slot, Orbitfall.
That said, Orbitfall isn’t just a simple nostalgia trip. The game flips the formula in an interesting way, as spaceship symbols move upwards, rather than aliens descending. Meanwhile, blocker symbols drop down, creating a dynamic twist on the classic concept. The action unfolds on a 6-column, 6-8 row grid, where spaceships land beneath rows of blocker tiles and a malevolent, multi-eyed cosmic entity lurking at the top of the screen.
Visually, Orbitfall looks far more advanced than Space Invaders, yet it retains an unmistakable retro-futuristic charm. A bleep-heavy soundtrack adds to the arcade-inspired experience, reinforcing its old-school roots. Fans of similar sci-fi-themed slots, such as Nolimit City’s Space Donkey or Inspired Gaming’s Space Invaders, may find Orbitfall a thrilling addition to the genre.
Much like dropping a coin into an arcade machine, players stake between $0.20 and $/€100 per spin, aiming to blast blockers, form clusters, and level up. ELK Studios rates Orbitfall a 7 out of 10 on the volatility scale, making it a medium-high volatility slot. True to ELK’s standard RTP model, the game features a 94% return-to-player rate.
As a cluster pays slot, wins form when 5 or more identical symbols connect horizontally or vertically.
Symbols & Payouts
There are eight regular pay symbols, divided into low and high pays:
- Low-paying symbols: Small versions of blue, green, yellow, and red spaceships.
- High-paying symbols: Larger versions of blue, green, yellow, and red spaceships.
Cluster Payouts
- 5-symbol clusters pay 0.25x to 1x the bet.
- 10-symbol clusters pay 2x to 50x the bet.
Wild Symbol & Special Symbol Sizes
- Wilds substitute for all symbols except the bonus symbol.
- A payline of wilds pays the same as the highest-value symbol.
- Symbols can appear in different sizes:
- Standard (1×1)
- Super (2×2)
- Mega (3×3)
- Larger symbols count as the number of 1×1 symbols they cover, and any empty spaces above them are filled with 1×1 symbols of the same type.
With cluster pays mechanics, multi-sized symbols, and wild substitutes, Orbitfall delivers a dynamic, arcade-style slot experience, blending retro sci-fi vibes with high-paced slot action.
Orbitfall: Features & Bonus Mechanics
Avalanche Wins & Level Progression
- Winning symbols are removed from the grid, causing remaining symbols to rise as new ones enter from the bottom.
- Avalanches continue as long as new wins form.
- Winning clusters destroy blockers—each cluster win destroys one blocker per column.
Level System
Orbitfall’s gameplay progresses through multiple levels, each adding more blockers:
- Level 1 → 5 rows of symbols, 1 row of blockers.
- Level 2 → 2 rows of blockers.
- Level 3 → 3 rows of blockers.
- Final Level → 1 row of blockers (blockers begin moving downward).
Advancing to the next level occurs when all blockers are destroyed.
- In Levels 2 & 3, remaining symbols carry over, and feature symbols appear more frequently.
- In the Final Level, each new symbol drop moves blockers downward, adding a new row of blockers at the top.
- The Final Level ends when a blocker symbol reaches the bottom row.
- Any active multipliers and redrops are carried into the Final Level when triggered.
Feature Symbols
Some blocker symbols contain features, which are released upon destruction:
- Redrops → Increases the redrop count. When no more wins occur, a redrop replaces all symbols while keeping blockers in place.
- Level Clear → Removes all blockers, triggering feature releases and advancing to the next level.
- Multiplier Symbol → Increases the global multiplier, which applies to all future wins in the same round.
Lazer Feature
- A 1×1 pay symbol may land with a Lazer feature.
- If part of a win, it charges the Lazer.
- When no more wins occur, a Lazer charge is consumed, removing an entire column of symbols.
Alien Attack
- At the end of a game round (when no more wins occur), an Alien Attack may randomly trigger.
- 1 to 6 columns are completely cleared of pay symbols, offering another chance for new drops.
Free Drops (Bonus Game)
- If a bonus symbol reaches the top row, it triggers the bonus round with 5 free drops.
- Any active multipliers and redrops are carried over.
- The bonus round cannot be retriggered.
X-iter (Bonus Buy Options)
For direct access to special features, X-iter mode offers various buy options:
| X-iter Feature | Cost | Effect |

Orbitfall: Slot Verdict
The retro gaming wave continues to sweep through the gambling industry, much like a fresh pair of vintage sneakers making a comeback. Many studios have embraced this trend, and it’s easy to see why—there’s a certain nostalgic charm in a slot that doesn’t chase cutting-edge graphics but instead leans into classic inspiration. While the old-school revival has been a force in the video game industry for years, slots like Orbitfall prove it’s gaining momentum in the casino world too.
Tapping into the legacy of a gaming icon like Space Invaders certainly adds to Orbitfall’s appeal. While its gameplay isn’t a direct copy, the spaceships, shooting mechanics, and vertical movement make the connection undeniable. That said, ELK Studios has ensured Orbitfall has its own identity, packing in unique twists and high-energy features.
Some of the game’s key mechanics include its feature symbols, which help clear blockers and extend gameplay, alongside the Alien Attack and Lazer Boost features. The global multiplier mechanic plays a pivotal role, increasing win potential as players progress. Meanwhile, the leveling-up system injects a mission-like objective, urging players to keep spinning in pursuit of the final level. However, just like in actual Space Invaders, progressing organically can be a grind, and if leveling up feels too difficult, it could sap motivation. That said, for those who persist, there’s a solid 7,500x win cap waiting to be conquered.
Whether or not the arcade-inspired up-and-down mechanics are your thing, there’s no denying that ELK Studios has once again flexed its creative muscles. Orbitfall may not become a runaway blockbuster, but in an oversaturated gambling market, there’s always room for original, inventive slots—and this one certainly earns its place in the lineup.
