It's possible there are a few treats I did not take into account (as the Red Line Map is missing some due to them having been claimed before the shot was taken) but I did reference the untouched map to find the locations of some.

Within the 17 day time period of the promotion (in reality - it's 18 days but the 18th day is not a full day) - I found that I was still 103 spaces short of Lovely Blue. To make up those 103 spaces:

Buying treats flat out - 53 passes (50 passes = 100 treats, 3 passes = 3 treats)

Using Titan's Challenges with my usual number of most and leats treats won each time with no failures:

Titan's Challenge - 6 treats won each time:
103 / 6 = 17 TCs
17 x 2 = 34 passes

Titan's Challenge - 10 moves won each time:
103 / 10 = 10 Titan's Challenges
10 x 2 = 20 passes

So on the Red Line route using Titan's Challenges...you are looking at between 20 to 40 passes.

Supposedly, it IS possible to complete the maze without needing to use Passes (but I suppose that doesn't rule out using things like the Titan's Challenge that you get in the exchanges or have saved) - but I've yet to figure out this calculation.

However, after running the numbers several times - I have come up with an average of passes needed IF you go the route of waiting for Treats in the Titan's Challenge:

10 to 30 passes depending on your luck and how many treats you win.

If you mean just buying the treats flat out...that calculation is dependent on where you are in the maze and what route you are taking.

If you followed the White Dot route, had the max. 5% regeneration rate, and waited until the last full day to buy Treats - you're still about 90-something spaces away from the end if you switch to following a more direct route and do not side track for additional treats.

So if you don't go for additional treats: 50 passes to get 100 moves to reach the end

If you DO go for the additional treats on the White Dot path - that's 39 extra moves...So now we'll call it 99 moves away from the exit:

99 - 39 = 60 moves short

To get those 60 moves: 40 passes for 70 moves *35 moves for 20 passes*
