The CAC Score Study5-part research series

Why We Built a California-Specific Score

Most online casino ratings are written for a global audience, which means they average away the details that decide whether a site actually works for someone in California. California has no state-regulated online casino market, so players here reach real-money games through offshore casinos that accept US customers. That reality changes what matters: the payment rails that clear for a US bank, support that answers during Pacific hours, and games that load in a mobile browser without an app. A generic five-star badge tells you none of that.

The CAC Score was built to close that gap. Rather than lift ratings from press releases, we surveyed a large, verified sample of California players aged 21 and over and paired their answers with our own hands-on testing of each casino. The number you see in the green poker chip is the output of that process, expressed on a single 0 to 100 scale so two sites can be compared at a glance.

What the Score Actually Measures

Every CAC Score is assembled from eight pillars, each capturing a different part of the experience: trust and licensing, payout speed and reliability, the fairness of bonus terms, the depth and quality of the game library, mobile performance, customer support, and the verified player survey that sits at the center of it all. We chose those pillars because they map to what California players told us actually shapes a good or bad session, not to what looks impressive in marketing.

Because the score is comparative, it is most useful when you read it against other sites rather than as an absolute grade. A casino in the high 90s cleared nearly every check we ran and earned strong marks from players; a score in the 70s flags specific weaknesses that we explain in the review. The CAC Score methodology page lists the pillars and their weights in full.

How to Use This Series

This is the first of a four-part look under the hood of the score. The next chapter explains how we sampled California using random and snowball methods, then we cover the statistical tests that keep the numbers honest, and finally how the eight pillars combine into one figure out of 100. Read together, they show why we trust the score enough to build the whole site around it.

A reminder on scope: the casinos we score are licensed offshore and are not regulated by the state of California. The CAC Score is a comparison tool for adults 21 and over, and it treats gambling as entertainment, never a way to make money. If gambling stops being fun, free and confidential help is available through the National Council on Problem Gambling.

Testing for Significance: T-Tests, Variance and Confidence Behind the CAC Score

An average can lie. We ran the California survey data through SPSS with t-tests, variance analysis and confidence intervals so that every number in the score earns its place.

Part 4

From Survey to Score: Weighting the Eight CAC Pillars Out of 100

Survey data on one side, hands-on testing on the other. Here is exactly how the two become eight weighted pillars and one number in a green poker chip.

The CAC team weighs in

The analysts behind the study talk through what this chapter means for a California player.

A national rating treats a California player like an average American. They aren't. Everything downstream — banking, legality, the casinos that even accept them — is different here.

Right, and the licensing badges national sites lean on have no force in an offshore California context. A ‘trusted’ seal doesn't help a CA player whose withdrawal stalls.

Which is exactly how a casino can carry five stars nationally and still frustrate the people we surveyed. The headline and the lived experience drift apart.

Aaron Whitfield

Banking is the cleanest example. Crypto cash-out speed matters far more to a California player than it does to a generic national audience, so it has to be weighted for them.

So we built a California-specific score, grounded in verified player data and published openly, so you can see why Ignition lands at 98 and a weaker operator at 75.
