Congratulations to CodeLegend for winning this challenge!

Intro
Alice is proud. She just finished her first Scratch project, a game of Tic Tac Toe. Impatiently she's constantly refreshing the project page to check whether someone already had taken a look at the product of her sweat and tears. And then there it is! A first comment:



What a jerk. He didn't even leave a like. But can you figure out, what Bob had in mind?

Rules:

1. Winner is, who first submits a project, that perfectly mimics the project of Alice.
   
2. For the project, you can use an unlimited amount of Boolean Blocks and Reporter Blocks, but you can only use a total of 2 of the other blocks (Hat, Stack, C, Cap and Custom Blocks). The number of blocks (not block types) counts, so if you use for example “show” twice, you already used up your budget on non-boolean-non-reporter blocks.
   
3. You can't use any custom variables or lists (no Data Blocks).
   
4. No hacked blocks.
   

What does “mimic perfectly” mean?
You don't have to create a pixel perfect copy of Alice' project (Bob already did that). Don't bother about visual details like fonts, exact size/position/shape and such. If your project COULD be turned into a pixel perfect clone without fundamental changes on the code, it's fine.
To be a valid solution, your project must have the following “features”:

• You have a “grid” with the marks ‘X’ and ‘O’.
  
• Red (X) always starts the game.
  
• A text tells the players, who's turn it is respectively what the final outcome of the game is.
  
• Every legal move is possible.
  
• No illegal move is possible (for example, you can't place your mark in an already filled square).
  
• Once the game ended (in a draw or a victory), the user can't change the stage any more (except by pressing the green flag).
  
• Green flag will restart the game.
  
• Besides the grid, ‘X’s and ‘O’s and the mentioned text, nothing can be visible to the user.
  
• Your project must be free of bugs.
  

This is a puzzle for coders, not lawyers. The goal is not to find legal loop holes, but to program with a limited selection of blocks.

switch backdrop to (some gigantic expression)

I would imagine so.

when [timer v] > (0)

Ok, so we have to reset when the flag is clicked, AND we have to run an action when the stage is clicked. so our hat block has to be

when [timer v] > (0)

Right?

Martin never said requiring noise to run the project wasn't allowed

I already tried that

Here's something, though…

So by boolean block do you mean a *populated* boolean block, ie including the expressions that form the boolean comparisons?

I'm pretty sure this can be done trivially with a tree of costumes, but there's rather a lot of them (this is the magic number you referred to earlier, right) and I don't have the patience to draw them all (in fact I think it would take me more than the 4 hrs to create all those costumes!).

All the text messages etc can be precomputed for each costume. The only logic needed is for moving from one costume to the next depending on which of the 9 squares you click in, which can be done with joining the current costume name with 9 booleans determined by comparing the mouse x and y against two horizontal and vertical boundaries.

Did I guess right? (Took about 3 seconds to come up with this, longer to type it, and it'll be much longer to implement it!)
