Owen Callister spent eight years on casino floors in Atlantic City before shifting to digital coverage of online slots and iGaming regulation starting in 2018. He has personally tested cashouts at BetMGM, Caesars, and Tropicana online, tracked RTP disclosures across a dozen WMS titles, and now covers slot mechanics, state legality, and bonus fine print for US players on this site. This directory is the result of that work.

What This Site Covers

The focus is one franchise: the WMS slot series most people search as invaders from the planet moola. That includes the original game, its sequel, free-demo options, and the real-money casinos licensed to offer it in the US. You'll find concrete numbers — RTPs, max wins, payline counts — not vague summaries.

The licensed casinos where you can play Planet Moolah are limited to regulated operators in New Jersey, Pennsylvania, Michigan, and West Virginia. Those are the only four states with confirmed real-money online availability as of this writing. Every operator named on this site holds a valid state license. No offshore platforms, no unverified brands.

How Owen Picks and Reviews Casinos

Each casino review checks four things: confirmed game availability, bonus eligibility (some casinos flag this title as ineligible for wagering with bonus funds), published RTP version, and payment method range. Owen has tested withdrawal flows directly at multiple NJ operators.

RTP gets special attention. Four reputable sources quote four different figures for this game — 92.97%, 94.1%, 95%, and 96.00%. The Planet Moolah RTP discrepancy guide explains why that happens and which version you're most likely encountering at a licensed US casino.

Editorial Standards

Facts come from operator pages, state gaming authority documentation, or the game developer's published materials. When a number can't be sourced, it isn't published. Bonus terms are flagged clearly — including why Planet Moolah may be excluded from casino welcome offers at certain properties.

Tax rules matter too. Slot wins of $1,200 or more from a single spin trigger a Form W-2G under IRS Topic No. 419. The US tax rules for slot wins page walks through what that means for players in NJ, PA, MI, and WV.

For state-by-state legal details, the which states let you play Planet Moolah for real money page is the right starting point. Each state section links to the relevant gaming control board.
