"Tic Tac Tow" rules: playing a game

Icono jugador

A TURN OF THE GAME

The player whose turn it is can write an S or an O on any of the empty squares.

If the letter you have just written, together with two other letters already written, form the word OSO horizontally or vertically, you can circle the word to score a point and also continue with your turn by writing a new letter, being able to chain several OSOs in a row in the same turn.

Si la letra que acaba de escribir no completa ningún OSO —o no se ha dado cuenta de ello…— pasará el turno al otro jugador.

SUBSEQUENT TURNS

Players will alternate turns playing always with the same mechanics.

OWNERLESS OSOs

If a player has completed a OSO but has not realized it, the other player can start his turn by circling the word and scoring the point.

This can be done with any OSO that is written and has gone unnoticed perhaps for several turns, but can only be done by the player who has the turn at the time.

Game over. Who wins?

Tips for playing "OSO"

icono consejo

TWO COLORS

To distinguish the OSOs of one player from those of the other, the ideal is to use two different colors, one for each player.

If this is not possible, then each player will mark their OSOs differently, e.g. one player may circle the word and another cross it out.

Variants

DIAGONAL

A more difficult variant also allows the word OSO to be written diagonally.

Games like "OSO"

OSO is a more interesting and difficult evolution of the classic Tic-tac-toe.

Connect 4 is a commercial game with a mechanic very similar to tic-tac-toe played vertically. You can check price and availability on the Amazon website.
