... And I like your printout of the board. I really did do a minimal version of the game for Python. Maybe someone else will do a fancy version in Python for comparison? --[[User:Paddy3118|Paddy3118]] 12:45, 5 February 2011 (UTC)
: I took that approach and added still more whitespace (for the REXX entry). To make the game board (grid) easier to see (without the reference numbers --- otherwise it gets cluttered/obfuscated pretty fast with any game board larger than nine cells) --- I removed the ''numbering'' grid and placed it to the right of the playing board (along with generous whitespace. --- this causes a reference game board (grid) to be displayed, making it a lot easier on the ole eyeballs to see who has what markers where, and what's available for a move (empty cell), and in specifying where to <strike>move</strike> place a piece/marker. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 16:18, 3 October 2017 (UTC)
A note on the REXX solution: the tic-tac-toe game, if played perfectly, will always end in a draw. Since kids may be playing it (or adults with very short attention spans), I programmed a "hole" in the logic so that if a human player plays first (the default), they may win if a certain pair of moves are made. -- [[User:Gerard Schildberger|Gerard Schildberger]] 23:49, 10 December 2012 (UTC)▼

It's not much fun playing a game ya can't win. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 15:52, 3 October 2017 (UTC)
=="ancient" computer game==
I'm surprised that BASIC, FORTRAN, and PL/I computer programming languages haven't had solutions entered (at the time of this posting). Tic-tac-toe was one of the first games written in any language as it was so simple to program and display. I still have my FORTRAN and PL/I programs laying around from the mid 1960s
== 3D tic-tac-toe ==
Has anyone thought of writing/entering a '''3D''' version of tic-tac-toe for Rosetta Code (as a separate task, of course)?
I imagine the programs would get a tad obtuse (hard to follow). -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 00:58, 17 April 2016 (UTC)

I wrote a PL/I program (the default grid size was 4x4x4) and it was (an infamous) favorite with the (IBM) OS/MFT operators (in Boston). No terminals with screens back then for our shop --- that was waaaaaaaay back in (cough-cough) <small>1970</small>, ... just the mainframe console (an IBM 1052 typewriter). A lot of time was wasted on the off-shifts and weekends, to be sure. A lot of operators volunteered to work on weekends, and the ''powers-that-be'' never caught on (or just didn't care). -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 00:58, 17 April 2016 (UTC)
The PL/I program had a '''4D''' capability, that is, after so many moves were done (this could be specified at game start), the oldest marker was ''removed'' from the playing grid. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 00:58, 17 April 2016 (UTC)
