Yes, it's possible to get at least 4x2x2x3 purples in the bonus spins, probably more. So say 48x15 @ 90 multiplier is 64,800x bet. Theoretically Bonanza can do say 48 ways of Diamonds (we've seen a screenie of that here in the base game recently) on a 20x multiplier which is 48,000x, more or less depending as with Donuts what multiplier you're on. Pie-in-the-sky admittedly but it will no doubt happen to some lucky bastard.
When I was speaking to the BTG chap via PM he did tell me that in testing it produced some colossal base game hits.
Well in that same article I read it said the following - on the very next paragraph...
I’m super exited to see more and more players winning big from Donuts network-wide launch on the 4th of July. The pay table spells out the potential, with a base game hit that can deliver 7 boxes, four of which will open up the same Donuts. The other 3 could hold up to x4 Wilds, you can do the math and that’s just the base game! The feature is another thing altogether but be warned – the game is as highly volatile as games can get (to date)!
So I'm assuming (I might well be wrong though) that the 7 boxes would be distributed as follows: One box on reel 1, two boxes each on reels 2, 3 and 4.
If that is the case, then would that make the potential max base game win 4 (box of 4 donuts) x8 (box of 4 donuts plus 4x wild) x8 (same as reel 2) x8 (same as reel 2) = 2048 ways of 4 purple donuts @ 15x = 30,720x?
The thing is though it says it is up to 2,401 ways to win (ie 7x7x7x7=2401). So I'm wondering how you can get 8 ways per reel on reels 2, 3 and 4?
Perhaps the maths in the game means that you can't have a box of 4 donuts and a 4x wild on the same reel,
but you can have a box of 3 donuts and 4x wild or a box of 4 donuts and a 3x wild?
Who knows, I certainly don't, because I've just not played it long enough.
Even in freeplay mode, I've yet to see a reel put out a combo of anything better than a box of 4 donuts and a 2x wild (or a 3x wild and a box of 3).
As for the bonus, the boxes are removed. And I'm not sure about this, but I haven't seen any 2x, 3x or 4x wilds during the feature.
So maybe all wilds in the bonus are 1x wilds.
But even if that is the case, the loss of those boxes and 2x - 4x wilds would be offset somewhat by the huge multiplier potential.
For the record Mr. D, I have seen the purple donuts fully stacked on reel 4 during the feature, so that means you can get at least 4x2x2x4 of purples in the feature, which makes it 64 ways @ 15x = 960x before you even apply the multiplier.
So it might well be that 100,000x is actually achievable.
