Quick tactics for this level
Tip 01
Check rows, columns, and diagonals before tapping any empty square.
Tip 02
If a move would create three of your marks or three of theirs, it is wrong.
Tip 03
Think of each board as a full stalemate setup, not as a winning move puzzle.
Step-by-step solution
On the first board, play as `X` and choose the empty square that fills the board without creating any final three-in-a-row.
On the second board, switch to `O` and again pick the only move that completes the board as a draw.
Ignore any square that would finish a row, column, or diagonal for either player.
On the last board, return to `X` and place the final mark in the remaining draw-safe square.
Confirm only when the full 3x3 is complete and neither side has a winning line.
Common mistakes
Mistake 01
Tapping the most obvious empty square without checking diagonals.
Mistake 02
Treating the board like a normal winning tic-tac-toe turn instead of aiming for stalemate.
Board notes
Layout
Level 66 shows three separate 3x3 tic-tac-toe boards with several fixed X and O marks already placed. Each screen tells you whether you are playing as `X` or `O` and leaves a few empty squares to finish.
Goal
End every board in a draw. You cannot make a winning line for yourself or allow the opponent to make one either.
Opening
The safe move on each board is the square that fills the board without creating a row, column, or diagonal of three. The first and last boards are played as `X`, while the middle board switches to `O`.
Danger Zone
The most tempting empty square often loses instantly because it creates a line. Level 66 only clears when the final board is a complete stalemate.
Mechanics
This is pure tic-tac-toe logic across three variations. The symbol you control changes, but the target never changes: force a draw.
