Slots are the most common type of gambling in modern online casinos. That is why the safety and reliability of slots is one of the most important criteria for choosing a casino. We will tell you what licensed slots are and where you can find them. We will compare legal gaming software and scripted slots, talk about game quality control, and answer frequently asked questions from players.
What do you need to know about licensed slots?
Licensed or fair slot machines are games from reputable providers that run on a random number generator and at the RTP set by the provider. Slot machines are almost never developed by the casino itself. The only exception is Champion Casino, which offers players its own software.
The most famous game developers:
- Pragmatic Play.
- Novomatic.
- Spinomenal.
- Betsoft.
- Playtech.
- 3 Oaks.
- Microgaming.
- Playson.
- Amusnet.
- BGaming.
Before registering at an online casino, go to the games section and check whether it has slots from the providers listed above. If the casino uses official software from well-known developers, it indirectly indicates the safety and legality of the establishment. For example, Slotoking has such a list.
All technical specifications, including the RTP (return to player), are published on the developer’s website. According to Ukrainian legislation, the RTP rate should be at least 90%, but most casinos buy games with an RTP of 94% or more. Slots with an RTP below 90% cannot be used in legal establishments. At First Casino , information about the RTP of licensed slots is available in the footer of the website.
How do licensed slots differ from scripted ones?
The main difference between honest software is the settings of RTP and volatility (an indicator of the frequency of winnings) of the developer. To ensure that the game is as fair as possible and depends only on luck, the casino should not make any adjustments to the operation of the slot machine. Licensed slots cannot be reprogrammed or changed in any way. They work according to the algorithms that were laid down by the provider. More than 5000 licensed slots can be found in the Cosmolot Casino gaming library.
Another difference between licensed and hacked slots is the absence of scripts. That is, programs that determine the “behaviour” of the slot. Scripted slots can be configured so that they never give winnings to some players, while others get winnings almost every spin. With the help of hacked games, dishonest casinos simply take money from some players and withdraw it through the accounts of others. You can find a list of licensed slots without scripts and hacks on the official website of Slots City.
Quality control of games
The fairness of games is checked by independent companies, such as eCOGRA, iTech Labs, Gaming Laboratories International (GLI) and Technical Systems Testing (TST). If games have been tested by these organisations, the link will be published on the main page of the official website.
In Ukraine, the Commission for the Regulation of Gambling and Lotteries checks the integrity of software. A casino can obtain a permit to operate only if it uses licensed slots. If the official website contains information about the licence, you can be sure that the casino games are fair and reliable. Look for information about the licence in the footer of the website, such as Pin Up.
