Caveats
Game logic relies entirely on the website, so there is no offline gameplay. However, there is still local gameplay! Additionally, sockets are not currently supported on the Picotron web player, so you'll have to load this up in the console to play.
I'm moving this to releases because everything functions as intended. I'd still like to add stuff, but I may start slowing down progress.
How to Play
This little diagram is all you really need to know. I'll elaborate below for anyone that still reads words (actual text!!!) in 2025.
Ultimate Tic-Tac-Toe has relatively simple rules that enable complex gameplay more similar to Chess than normal Tic-Tac-Toe.
The absolute MOST IMPORTANT thing to know about this game is that you choose where your opponent moves next. The green squares — indicating which squares are active, or allowed to be played in — are based on the previous move. This means that the most important part of your move might not be where your piece goes, it might be keeping your opponent away from where they want to go! This means lookahead is very important: "If I send my opponent here, they're probably gonna go there, which would set me up to..." and so on.
You can determine where your opponent will end up by thinking of each board as corresponding to the bigger board. When I play in the top left of any smaller board, my opponent will be forced to play in the top left board. This is a bit more complicated on the larger sized game boards, but the concepts are still the same.
But what happens if the board I sent my opponent to is already won, or full! You simply get to play anywhere else in the next layer up! On the 2-depth board, this means you get to play anywhere! Again, this is more complicated on larger boards, but they follow the same set of rules.
Also!!! The win condition isn't just claiming the most boards. You still have to get a three-in-a-row to win! Here, X won the game by winning a diagonal of boards in a row!
Controls
Everything should be decently self-explanatory. All functionality is exposed to the mouse and is just point and click, with the scroll wheel used for navigating screens. Those playing on controller or Picotron's keyboard-controller mappings can refer to the following (button descriptions for an Xbox controller):
- Navigate with
- Controller Left stick / Right stick / D-pad
- Keyboard WASD / Arrows / HJKL (Vim-like)
- Mouse cursor - Select with
- Controller A
- Keyboard C or Z
- Mouse left - Go back or zoom out with
- Controller B / X
- Keyboard F / X / V - Backspace with
- Controller X
- Keyboard X / V - Toggle between default focus & left panel with
- Controller Y
- Keyboard G - Page up and down with
- Controller Left bumper / Right bumper
- Keyboard Q / E
- Mouse wheel up / down
- Moving up or down with default navigation, in most menus
