You deposit money, play a few rounds, and start wondering if something’s off. The cards seem stacked. The spins feel rigged. But how do you actually know?
I’ve tested dozens of casinos over the years, and I’ve figured out which checks separate legit platforms from sketchy ones. You don’t need a degree in statistics or access to source code. You just need to know where to look.
Before running these tests, pick a trustworthy platform. RetroBet Casino processes withdrawals in 24-48 hours and lists 2,000+ RNG-certified games with a NZ$15,000 welcome package—perfect for systematic fairness testing without withdrawal obstacles skewing your data collection.
Check the RNG Certificate (And Actually Read It)
Legit casinos get their Random Number Generators tested by outside labs. You want certificates dated within the past year—anything older means they’re coasting on old credentials. The names that matter: eCOGRA, iTech Labs, Gaming Laboratories International.
My routine? Scroll to the footer where casinos dump their legal stuff. Look for certification badges. Then I click the badge. Does it link to an actual certificate with the casino’s name, testing dates, and which games got checked? That separates real certification from window dressing.
Massive red flag: badges that don’t link anywhere or dump you on the testing lab’s generic homepage. I stopped counting after twenty casinos doing this.
The certificate should list which games were tested. If you’re playing slots, make sure slots are specifically mentioned. Some casinos certify live dealer games but run uncertified RNG games on the side.
Track Your Session Results for Patterns
This takes time, but it’s the most revealing test you can run yourself.
I pick one game and play at least 100 rounds at minimum bet. Then I record everything: wins, losses, bonus triggers, specific outcomes. After several sessions, I compare my results against the stated RTP and hit frequency.
Example from my testing: I played a slot claiming 96% RTP and “frequent” bonus rounds. After 500 spins, I triggered bonuses only 3 times (stated frequency was 1 in 100 spins). My actual return was 89%. That casino failed.
Look, 100 spins won’t give you perfect math. Variance messes with small samples. But stretch it to 500-1000 rounds and the numbers should start matching casino claims. When they don’t—that’s your warning signal.
Lazy tracking trick: Screenshot your balance every 50 or 100 spins. Note when bonuses hit. Takes five seconds per screenshot. Now you’ve got actual numbers instead of relying on memory.
Test Withdrawal Speed and Accuracy
Fair casinos process withdrawals as advertised. Unfair ones create obstacles.
My standard test: I make a small deposit, play a bit, then immediately request withdrawal of my remaining balance. If you want to risk even less, $3 minimum deposit casinos let you run this same test for pocket change.
Here’s what I watch for: Do they ask for documents they already have? Does the withdrawal take longer than advertised? Do they suddenly enforce wagering requirements not mentioned at signup?
I once tested a casino advertising “instant” crypto withdrawals. My withdrawal sat “pending” for 48 hours, then they requested ID verification despite me having verified during signup. That told me everything about their operation.
Run the Same Bet Test
This is my favorite quick test for live dealer and RNG table games.
I grab the simplest bet available—red in roulette, banker in baccarat, whatever. Place it 50 times straight at the same amount. Then I calculate how my win rate stacks up against what the math says should happen.
Example from last month: I put 50 bets on banker in baccarat. The math says banker wins about 45.8% of hands. My actual results: 21 wins (42%). Close enough to pass. If I’d won only 15 times (30%), that would trigger deeper investigation.
This test won’t catch sophisticated manipulation, but it catches crude rigging. Any result more than 15-20% off from expected probability deserves suspicion.
Check if Games Behave Differently at Higher Stakes
Some shady casinos run fair games at low stakes but alter outcomes when money gets serious.
Here’s my setup: same game, minimum bet, half an hour of play. Then I jump to 10x or 20x that minimum and play another half hour. I track hit frequency, bonus triggers, and win distribution.
The results should be proportionally similar (accounting for variance). If the game suddenly turns ice cold when you increase stakes, that’s your answer.
The Reality Check
These tests won’t catch every form of cheating. Sophisticated manipulation can fool even careful players. But they’ll catch the most common forms: fake RNG claims, altered payout rates, and withdrawal scams.
I’ve abandoned half a dozen casinos based on failed tests. Every single time, I’d find other players posting about the same problems I’d documented. Your tracking data beats the casino’s marketing copy every time—it’s the one part of the relationship where you’re getting straight answers.
