It only takes 2 years to become a god: Pokemon Platinum scientist achieves omniscience by beating 4 billion versions of the RPG at the same time with the power of math

Somehow, it's possible to beat all 4,294,967,296 permutations of Pokemon Platinum simultaneously using the same button presses, as long as you can simulate a full multiverse of timelines and account for their worst-case scenarios at all times.

If you're already confused, that's understandable. The thing is, Pokemon's random number generation isn't truly random. When you load up a game of Platinum, it's assigned a 'seed' – one out of over four billion possible options – and 'random' events like Pokemon encounters and Shiny finds will play out differently depending on what seed you're playing on, in a pre-determined way. Since 2022, content creator MartSnack has been working out what actions you'd have to take to beat all of these seeds using the same button presses at the exact same time – something only possible because each seed's random events are essentially being mapped out in advance. Using the power of simulation, this Pokemon professor could become omniscient – with knowledge of everything that'd happen at any moment across the Platinum multiverse. 

But to play through over four billion timelines at the same time, you've got to consider the worst things that can happen. Not necessarily in a dramatic sense, but for example, encountering a wild Pokemon in the tall grass will usually take you between six and 17 steps. However, because MartSnack's seed-tracking simulator shows it can take up to 195 steps, they had to take that many steps every time they wanted to battle a wild Pokemon to keep all the games in sync. 

Keeping things in sync is a constant battle in itself, though. As MartSnack explains, when it comes to level grinding, the fluctuating amount of EXP earned across the different timelines (thanks to encountering varying Pokemon) means that the alternate seeds gain level-ups at different rates, therefore making Pokemon attempt to learn moves and attempt to evolve at different speeds. Thankfully, these things could be used to MartSnack's advantage with a
