Lets say you play mostly at Microgaming casinos. I wonder if other casinos' RNG's are familiar with your style of play, or have a record of your winnings at other MG casinos. Food for thought.
I would be very surprised if they did. Playing RNG is pretty close to throwing money down the drain, these things are fixed to take your money once you win x amount of £££££$$$$$$$$$$s. I am not saying all RNG'S are cheating but some i have played have shown that they do indeed cheat.
Perhaphs when we switch to an actual TRNG (as paid RNG's use) then those are sort of "limitless", they don't obey or care about the usual "roulette limits" we are used to; it may have to do with the dynamics of the ball falling on disk zones at a rythm, and the actual way the numbers are distributed at the wheel. Meaning with roulette we are used to experience a certain "cadence" in the stream of numbers, and we get "signals" out of them, but TRUE random... a beast of its own.
-Not necessarily cheating, just not being roulette.
