I'm enraptured by this Zelda maniac who worked out there are 1 quadrillion 83 trillion 414 billion and 90 million possible permutations for a dog race in Majora's Mask

pcgamer.com:

Yes it's a Zelda game, but bear with me because this is a story only possible on PC. The Legend of Zelda: Majora's Mask was first released on the Nintendo 64 in 2000, and since then has been the mainline entry that all the cool kids say is best. There are plenty of reasons for this, from the grim and unsettling atmosphere to the brilliant Groundhog Day structure, but one of the enduring appeals is all of the game's mysteries.

Most of these are intentional and authored by Nintendo, but some are not. And one of the biggest unresolved questions about Majora's Mask is about a dog racing minigame where, to put it mildly, the odds are heavily stacked against one blue dog in particular.

Yep, this is an underdog story. At the back of Romani Ranch there's a location called Doggy Racetrack, where the player finds 14 dogs: Four are coloured white, three beige, three gray, two brown, one gold and one blue. Link can place a bet on any dog and then watch a race play out… except not all dogs have been created equal.

First of all, the game is designed in order for the player to exploit it. Once Link has obtained the Mask of Truth, you can equip this and pick up the dogs to tell what they're thinking: Dogs with happy thoughts are likely to finish higher, while dogs that are under the weather are a bad pick. On top of this, the gold dog is a bit of a winner, and when his thoughts begin with «ruff» a first place finish is highly likely.

The blue dog, on the other hand, is one of life's losers. So much so that the blue dog is a kind of mini-meme within the Majora's Mask community: It just never wins, to the extent that everyone thought (not unreasonably) it couldn't win. There are several factors going into this but, in order not to bore you with math, the blue dog has a lower base speed than all the other dogs and, despite there being a small element of RNG to this base speed calculated on each frame, over the course of a race that is going to hurt it relative to the rest of the pack.
