Two versions of this game exist, and they play very differently. The original invaders from the planet moola slot runs 25 fixed paylines, medium volatility, and a widely cited 96.00% RTP. The sequel, Invaders Attack from the Planet Moolah, pushes volatility to high, expands paylines to 5–50, and tops out at 3,750 coins — 50% more than the original's 2,500-coin ceiling.
Which version should you play?
Depends on your risk tolerance. Medium volatility means the original pays out moderate amounts at moderate frequency. High volatility on Attack means longer dry spells, but the ceiling is higher. Know your bankroll before you choose.

Where can you play each version?
The original is available for real money at BetMGM, Tropicana, Caesars, and Bally Casino — all licensed in at least one of NJ, PA, MI, or WV. You must be physically inside a legal state when you play; geolocation software enforces that rule hard.
Invaders Attack is a different story. No confirmed US real-money online version exists as of this writing. It lives primarily on land-based cabinets, including Class II tribal gaming machines regulated under the Indian Gaming Regulatory Act. Sites suggesting otherwise deserve skepticism.

Watch the RTP numbers closely
Four reputable sources cite four different RTPs for the original: 92.97%, 94.1%, 95%, and 96.00%. That spread is real — operators license different software configurations. Always check which version your casino runs before depositing. The Planet Moolah RTP discrepancy guide explains why the numbers differ and how to find the right figure for your platform.
Also note: some casinos mark this game as ineligible for bonus wagering. That means welcome deposit matches cannot be played on it. Check terms before you claim anything. The bonus term warnings page breaks that down in plain language.
