It would not surprise me at all if MG slots are weighted, after all, even a child can see that the 3-reel slots are weighted, so why not the 5 reel?
Take for example TR2, the Global Adventure bonus.
The first 4 passports always drop within the first 50 spins, then you wait forever for that last one to hit.
I went well over 700 spins once (multiple sessions) to hit that last passport on reel 1!!
Centre Court, another one thats weighted, has nobody ever noticed that there are tennisballs added to the reels at certain points in the game?
Ever since that November update the reels are spinning so slow that I can watch every symbol pass by, and reel 1 and 5 have sometimes 1, sometimes 2 tennisballs on them.
And I'm almost sure that during the high paying freespinrounds there are more stacked wilds on the reels also, 2 sets of 3 instead of 1.
Dynamic weighting, yes I'm sure it happens, but does this mean the games are rigged?
Anyone can observe these things.
Play World cup and you have the same effect sometimes you will have 1 whistle on reel 5 sometimes 2. hit a decent free spin round and back to 1 whistle. It is that obvious but still it is klike banging my head against a walll most of the time.
Thank you for your observation and the valid point you make.
