After thinking about this a bit further: even though the fact that the number indicates reel position and not 'predefined reelset', it doesn't change my original complaint. It enhances chances of winning combination (200 long reel which lands on position X and 1-7 of these blocks are visible). However, this DOESN'T change the fact that if the reelsets are not changed every spin, then every spin doesn't have an equal chance of winning. eg:
The first reelset is set to 200 of the same symbol (very unlikely, but basically possible). If this reelset is stuck for any amount of spins (eg. an hour), would you say I have equal chance in winning on every spin? (@trancemonkey , any opinion on this?)
As I said on my original post, the position of two 9s was the same after 40 minutes of play. How probable this is if the reelset was changed between the spins?
The bit in bold makes no sense whatsoever - why would reel positions change?
If i define a reel as:
The if the RNG picks 4, it will display a K at the top left position and then a 10 and GOLD below it (assuming 3 positions on a reel). These positions CAN NOT change. It doens't matter whether you play it for an hour, a month, or 10 years, position 4 will always display a K. The RNG just randomises the position displayed, as it should.
The reel band is fixed. The fact you see the same symbols at the same reel position is 100% proof of nothing more than position 44 has two 9's at it.
One the test ALL test houses do in my experience is that they force a specific number (sometimes force a seed) in to the RNG to make sure that the same outcome happens if the same number occurs to prove that the game does exactly the same thing with the same random number. For example, if you set a mersenne twister RNG to have a specific seed, you will get the same sequence of numbers - this way you can test to see if a game is doing what it should, because the sequence of games should always be the same if you start with the same seed.
Obviously under normal usage, you never use the same seed, and the seed is randomised from something that makes it impossible to guess / work out / know.
