OnlineSlotsRealMoneys doesn’t run any games. This page explains how fairness works at the casinos we review and the checks we make before listing them.
What an RNG is
Every online slot, card game and roulette wheel that isn’t live-streamed uses a random number generator (RNG). It’s software that produces an unpredictable sequence of numbers, and each spin or deal is decided by the number drawn at that instant. Past results have no effect on the next one: a slot isn’t “due” to pay.
Return to player (RTP) is a separate figure. It describes how much a game pays back on average over millions of rounds. A slot with 96% RTP doesn’t return C$96 for every C$100 you bet in a session; it means that over a very long period, that’s the average.
Who tests the games
Licensed casinos and game studios must have their RNGs and games certified by independent testing laboratories. These labs check that results are random, that the published RTP is accurate, and that the game can’t be changed after certification. Well-known labs include:
- eCOGRA
- GLI
- iTech Labs
- BMM Testlabs
Regulators such as iGaming Ontario, the Malta Gaming Authority and the Kahnawake Gaming Commission require this testing as a condition of a licence.
What we check before listing a casino
- A valid licence we can confirm on the regulator’s public register.
- Games supplied by established studios, not unbranded or copied titles.
- Testing certificates or seals that link to a real lab certificate.
- RTP figures shown inside games or in the casino’s help pages.
- Clear terms on how game malfunctions and disputed results are handled.
If a casino fails any of these, we don’t list it, whatever commission it offers.
Check it yourself
- Scroll to the casino’s footer and find the licence number and regulator.
- Search that number on the regulator’s own website, not through the casino’s link.
- Click any testing seal. It should open a certificate on the lab’s domain.
- Open a game’s info panel and compare its RTP with the studio’s published figure.
Live dealer games
Live tables use real cards, wheels and dealers streamed from regulated studios, so results don’t come from an RNG. Fairness here relies on studio licensing, camera coverage of every round and audited procedures for shuffling and dealing.
If you suspect a problem
Note the game, time and round ID, and take screenshots. Contact the casino first; licensed operators can review the round in their logs. If you’re not satisfied, complain to the regulator named in the casino’s licence. Please also tell us, so we can review the listing.
