About Fish Tic Tac Toe
Fish Tic Tac Toe changes the board over time. Each player keeps three marks; placing a fourth removes that player's oldest one. Make a line before the twelve-placement draw, taking account of which mark disappears next.
How to play Fish Tic Tac Toe
Place a mark in a legal empty square and watch the oldest-mark order. Once you have three marks, the next placement replaces the oldest. The board can reopen a square that would stay occupied in ordinary tic-tac-toe.

Make a line before your oldest mark washes away
Two marks may appear to promise a winning third square, but if one of those marks is the oldest and you already have three, it disappears when you make the next placement. Recalculate the line after removal, not just before it.
What to plan before your next move
Track both players' oldest marks. A threat can expire on the opponent's next turn, while an apparently blocked route may reopen. Count the placement limit as well as possible lines so you do not plan a sequence that runs past the draw.
Fish Tic Tac Toe or Tic Tac Toe?
Tic Tac Toe normally keeps placed marks for the round. Fish Tic Tac Toe limits each player to three and removes the oldest on the fourth placement, turning static blocking into a moving-order puzzle.

Common questions
Why did one of my Fish Tic Tac Toe marks disappear?
You placed a fourth mark. Only three remain per player, so that player's oldest mark washes away.
