Tic tac toe 5×5

5×5 tic-tac-toe fills twenty-five cells. House rules vary: some want five in a row, others play “get four on a five” — either way it is a longer think than classic three-in-a-row.

The playable 5×5 engine is a later phase. Today you get the rule card plus a live classic 3×3 for warm-up marks and vs-AI practice.

Defaults

Assumptions

Live board today is classic 3×3. We describe common 5×5 conventions; we do not claim a finished 5×5 AI yet.

Steps

How

  1. Note twenty-five cells and your table’s win length (five-in-a-row or four-on-five).
  2. Practice priority moves on the classic 3×3 above.
  3. Use Hint for a cell plus a one-line reason.
  4. Return when the real 5×5 board ships.

Worked notes

Examples

  • Five-in-a-row on a 5×5 → a full line across the board wins under that house rule
  • Friends prefer four-on-five → agree before you start — shorter win condition, different fights

Watch-outs

Gotchas

  • Printable giant boards are not this page.
  • Do not confuse with ultimate’s nested boards.
  • AI search for 5×5 is heavier than 3×3 — that is why it ships later.
