There is more money in the new machines than in the old ones.
It sounds very plausible especially when the time comes to release a new slot. Some players casino online believe that this is a tricky way to attract more visitors. That it is only disclosed in secret and is kept secret by professional gamblers. There is a perception that in the first months after the slot is released, it deliberately gives more money, thus attracting more players. Once the deadline has expired, the machine starts taking the money.
This is impossible, just like changing the payout percentages. In the world of gaming industry, there are strict laws that simply do not allow extra movement. Special checks are carried out quite often to detect such illegal activities. Slots are unpredictable games for good luck. Everything is based on a random number generator running a special encrypted algorithm.
