Invaders Attack from the Planet Moolah online is the high-volatility sequel to the original WMS slot — and the single biggest difference from its predecessor is where you can actually play it: primarily on land-based cabinets, not through a licensed US online casino. Before chasing it on a website, here's what to know.
What Is Invaders Attack from the Planet Moolah?
Light & Wonder (formerly WMS) built the Attack sequel to push the franchise further. It keeps the alien-cow theme and cascading reels mechanic but cranks up the risk profile considerably. Variable paylines run from 5 to 50, compared to the fixed 25 in the original. Maximum payout jumps to 3,750 coins versus 2,500 coins on the base game.
Volatility is rated high — a meaningful step up from the original's medium rating. That means longer dry spells between wins, with the upside of bigger hits when they land. Land-based RTP can be configured anywhere from 85% to 95% depending on how the host casino sets the machine, so location matters more than usual here.
How Invaders Attack Differs from the Original
| Feature | Original (Planet Moolah) | Attack Sequel |
|---|---|---|
| Paylines | 25 fixed | 5–50 variable |
| Max payout | 2,500 coins | 3,750 coins |
| Volatility | Medium | High |
| RTP (online) | 96.00% (most cited) | 85–95% (land-based config) |
| US online availability | NJ, PA, MI, WV | No confirmed online version |
| Gaming class | Commercial (Class III) | Class II tribal version exists |

Is Invaders Attack Available Online for Real Money in the US?
No confirmed US-regulated online casino carries Invaders Attack for real-money play as of this writing. It is primarily a physical cabinet found at tribal and commercial properties. Anyone claiming otherwise — especially unverified third-party sites — should be treated with skepticism. Always check the license through your state gaming authority before depositing.
If real-money online play is the goal, the original title is the right choice. BetMGM Casino carries it in NJ, PA, MI, and WV. The Invaders from the Planet Moolah slot machine full review covers that version's paytable, bonus trigger, and what to expect at each operator.
Where Can You Play Invaders Attack?
Land-based is the answer for now. Tribal casinos operating under Class II gaming licenses — regulated under the Indian Gaming Regulatory Act — have carried the Attack cabinet. Physical machines at properties like Robinson Rancheria Resort & Casino have been documented with this title.
For free-play only, Jackpot Party social casino offers both the original and Attack titles using virtual coins. No real-money payouts are possible through Jackpot Party — it's strictly for entertainment.
RTP Variance: What the Numbers Actually Mean
The land-based RTP floor of 85% is a real concern. On a physical Attack machine at a tribal property, the house may configure it significantly below what online players see on the original. That's a 10-plus percentage-point gap in some cases. The Invaders from the Planet Moolah RTP guide explains why four reputable sources quote four different return figures — and how to find which version a specific casino runs.
States, Taxes, and Responsible Play
Even on land-based machines, US gambling winnings are taxable income. The IRS requires casinos to issue Form W-2G for slot wins of $1,200 or more from a single spin, per IRS Topic No. 419. Keep records of wins and losses.
