But, what the the best RTP slots in the UK, and where can you play them? Though the industry average is 96%, the RTP of slots can vary wildly depending on the publisher, casino, and other factors.

Another approach instead of basing the measurement on a number of days could be to measure once X number of plays has been achieved. A wider date range (for example, measuring a rolling 90 days of activity) could be measured in parallel so that a greater volume of play is considered (meaning the data will have a much finer tolerance). It will be up to the licensee (often based on the game designer’s instructions) to determine the measurement approach and frequency. One measurement failure does not confirm the game/RNG is faulty, however sequential failures or a number of failures over a given frequency of measurements might. The confidence interval should not exceed 99%, this would mean a non-defective game might fall outside range approximately only 1 in 100 tests. This would mean a non defective game might still fall outside range approximately 1 in 20 tests.
