Do Players win less in Real-Money mode Online Mines Games
1. Overview
The short answer to this question is no, they do not. If you play long enough, you will inevitably reach the advertised theoretical return of your chosen game. All online casino games operate on random number generators (RNGs) and this applies to both their demo and real-money versions.
2. The Process of Random Number Generation
The RNG produces ridiculously complex and long strings of numbers to determine each outcome in a given game. The process continues at all times even when no one is playing the respective game. To use slots as an example, the random number generator decides the result in a split second the moment you hit the spin button.
The string of numbers it stops on determines which symbol will appear in each position on the reels, producing either a winning or a losing combination. The process of random number generation ensures all games produce unbiased and unpredictable outcomes, in both free and real-money mode.

3. Licensed Casinos Do Not Manipulate Their Free Games
Online gambling operators, when properly regulated, will never attempt to purposefully manipulate the free versions so that they yield more winning outcomes than the real-money variants. Such practices are not only unethical and nefarious but also illegal.
Offering demos with higher return percentages than the real-money versions is a flagrant violation in most jurisdictions with regulated gambling markets. Increasing the RTP of the demo games is generally prohibited as it will cause players to have false expectations when they switch to real money.
4. Confirmation Bias during Free Play
If you happen to notice you win frequently during demo play but start losing when you transition to real-money bets, you are most likely experiencing confirmation bias. This is a form of cognitive bias that causes people to subconsciously look for patterns that validate their preexisting beliefs.
When you experience pronounced differences in win frequency, you are simply observing variance and standard deviation in action. Both phenomena are an inseparable part of gambling and are inherent to all games of chance, including online slots, roulette, and baccarat.

A Real-Life Example of Higher RTP in Demo Mode
There have been claims in the past that some software providers intentionally alter the theoretical return percentages of their games so that bigger and more frequent wins occur during free play compared to the real-money versions. One example that comes to mind is the incident with an online slot developed by the GameArt software studio.

Closing Thoughts
Players at licensed and strictly regulated gambling sites have no reason to fear the demo versions of casino games could have different characteristics than the real-money ones. Online casinos rarely use proprietary software and typically offer games developed and configured by third-party suppliers.
Even if there is an issue of this kind, both parties involved will step up their efforts to ensure it is resolved as soon as possible, as you saw from the case we discussed earlier.
Multiple safeguards are in place to prevent such misleading practices. Both software companies and gambling operators undergo regular audits to ensure their games yield their advertised returns in both free and real-money mode.
