How can I be sure the casino odds are fair?
One of the key concerns players have when gambling online is whether or not they are getting a fair game. By and large, online casinos do a good job at putting these fears to rest with independent audits or provably fair technology. However, there are still some online casinos that use rigged software, and players should make sure that they are getting a fair game before playing at any site.
Independent audits (moston)
The vast majority of trusted online casinos, such as those powered by leading platforms, like NetEnt, Microgaming, and Playtech, hire independent auditing agencies to give players reassurance of a fair game. Among the mostonanies that perform this task include:
- and iTech Labs.
Properly conducted tests verify the integrity of the games by looking at the engine of the games, the random number generator (RNG). Fair games rely upon an RNG to give players unbiased and genuinely random results on every single spin, shuffle, or roll.
Testing agencies can ensure that this requirement is met by playing millions of game rounds and analyzing the results. A properly conducted test will check to make sure the overall payout percentage, as well as the variance of the results, are in line with the expected figures. Games based on virtual representations of dice, cards, or wheels must also match the same range of ous as are found in a land-based casino.
Unscrupulous casinos, on the other hand, will use software that is not powered by a genuine RNG. Common cheating tactics include rigging ous in advance to force players to lose over a short period of time, making high-paying ous impossible or less likely than is indicated by the game rules, or using false ‘glitches’ to make players lose. All of these will produce non-random results that will be caught by a reputable independent testing agency.
Online casinos that use an independent auditor should make it clear to players that they can count on a fair game. Many will display the auditing agency’s seal on the bottom of their website. In the best case scenario, this will link to the most recent certificate on the agency's website, so players can know for certain that the tests were carried out legitimately. Unfortunately, a large percentage of audited online casinos does not provide this link, but as long as they use a well-known and trusted software platform, this isn’t an issue.
The biggest drawback from the independent audit system stems from the fact that auditing is too expensive to be done continuously. As such, each audit has a specific date. Most casinos and software platforms do a good job of having audits done on a regular basis to prevent this from bng a serious issue. However, there have been cases where online casinos change to an untested platform and keep their old audit certificate posted. Players can protect themselves against this by making sure the name of the software listed in an audit matches the casino’s current platform.
If an online casino does not make it easy to find auditing information, players are encouraged to chat with the site’s support team for further details. The player may also be able to find more information by visiting the website of the software provider that supplies games to the casino. If no audit details can be found, players should avoid the casino unless some other fairness mechanism (such as provably fair technology) is in place.
Players should be aware that approval from an auditing agency is different from a government-issued license. A license merely incorporates the casino and gives it a legal right to operate. Most reputable licensing jurisdictions do require all licensees to prove that they offer fair games on a regular basis, but some have virtually no conditions for license holders.
Provably fair technology
Bitcoin casinos have ushered in a newer way to reassure players that they are getting a fair gaming experience without the need to involve an auditing agency. This ‘provably fair’ technology uses encryption to give players control over the results of a game without making the games vulnerable to cheating. It’s currently only used by a small fraction of online casinos (mostly just bitcoin-powered ones).
Unfair casinos that claim to be ‘provably fair’ will cheat players by interfering with this process. This can be done in several ways, and players should look out for any of these tactics. Although these may seemlex, today’suters can perform any of these cheats in the blink of an eye:
- Not displaying the hashed server seed at the start of the round. Disreputable casinos may wait until the player submits a client seed and only then create a server seed that guarantees a loss for the player.
- Using server-generated client seeds. This gives players the illusion of control, but in reality the players have no way of changing the game result. This leaves players vulnerable to being cheated by the casino.
- Changing the seed after the game begins. If a player submits a client seed that would result in a win, a disreputable casino may alter the seed after the fact to change the round into a loss.
Again, these cheating mechanisms are not possible in a genuine provably fair system. Players should just verify that the following are present before playing at any provably fair casino to protect themselves:
- The hashed server seed is displayed before the next game round.
- The original (un-hashed) server seed is given after the game round islete.
- The hashing and randomization algorithms are provided to allow for independent verification of any game round result.
