App Description

Tic Tac Toe ⑤ (Five in a Row) is a strategic board game also known as Caro in Vietnam, Omok (오목) in Korea, gomokunarabe (五目並べ) in Japan and wuziqi (五子棋) in China.

It is the extended version of Tic Tac Toe - you win with 5 pieces in a row instead of 3. The board is 15x15. The game is also sometimes called XO.

Players alternate turns placing X or O on an empty intersection. X makes the first move.

The first player to get an unbroken row of five stones wins the game.

Caro X brings this great game to your iPhone. You can enjoy Caro in family game time, or you can also enjoy the game by playing with the AIs of varying difficulties. Beware that it is very challenging to beat the best AI in this game!

You will also gain experience points by winning against the AIs (+1 for Easy, +3 for Medium, +5 for Hard, and +7 for Expert).

Features:
◆ Undo
◆ Save/load unfinished game
◆ AIs with 4 levels of difficulties
◆ Timer based game
◆ Zoom in and zoom out.

The variation of Five in a Row supported in this game is free-style. A player just needs to make a row of five or more stones to win.
