Multitasking

Part of Confounding Calendar 2022 (https://confoundingcalendar.itch.io/)

Goal: win all three games of Tic-Tac-Toe concurrently

Bad news: all three games are against a perfect, unbeatable AI opponent
Good news: you can multitask and play more than one game at a time (?)

Extra challenge: this puzzle is winnable "blind" (without seeing the opponents moves or the game state)

There exists a fixed, sequential set of instructions—with no conditionals/ifs— that will win 100% of the time against any opponent, regardless of its exact moves (including an antagonist who has access to your complete plan in advance). 

Imagine I covered up the game UI with a black overlay and replaced the AI with a new one that you know nothing about (don't worry it still has to play by the rules). Assuming you've planned well, you should still be able to get a guaranteed win just by carefully clicking around in the darkness!

Can you find this unbeatable strategy?

Developer notes: I've been toying on-and-off for a while on a 3D first-person puzzle game using Tic-Tac-Toe as its core mechanic. This was an intentionally silly idea to challenge myself and practice puzzle design, but I ended up uncovering a surprising amount of depth and some really cool puzzles. Sadly, it's not likely to ever release (it's become quite large and I've grown too attached to it, so it would be a lot of work to finish to my satisfaction!). But this particular puzzle from the mid-game works relatively well standalone, and it's a shame for none of these puzzles to see the light of day, so I've adapted and restylized it for 2D / web as part of https://confoundingcalendar.itch.io. Hope you enjoy!
