Hard Tic Tac Toe Game Online - 1 & 2 Player Modes

Rating: 5.2/10 - 84 votes

Trio Tic Tac Toe is a fun, tough and addicting X and O game to play against the computer in 8 different difficulty levels, or with a friend in 2 Player mode. Here, each player is limited to just three pieces, and must continue to move these pieces around the grid while trying to score three in a row or thwart their opponent. Tic Tac Toe online has never been so tricky!

Reasons to play this innovative version of Tic Tac Toe: With a maximum of 6 filled spaces on the grid at any one time, this cool online version demands a lot more interesting tactical play compared to the classic Tic Tac Toe format. Young and older players alike, and experienced strategy puzzle aficionados should enjoy the challenging action here. Can you become an expert Tic Tac Toe player?

Strategy to win: Good analytical thinking skills are very important here, especially if taking on one of the more difficult computer levels. This is a much more tactical thinking-based version of Tic Tac Toe than versions you may have played before. Instead of looking to score three in a row with the knowledge that you may have an unlimited number of Xs or Os to use, here you must be more forward-thinking and cautious with your moves. You have to be more defensive-minded also - not to open up an extra space for your opponent (computer or friend) to exploit if you are removing one of your earlier moves.

How to Play: A Flash-based, logic puzzle game for notebook, laptop and desktop PC / Mac (with certain browsers). Note: Some of the instructions on the game face mention iPhone / mobile devices. However, this addicting version is a Flash game only!

In Trio Tic Tac Toe, your goal in each game is to score Xs or Os three-in-a-row, horizontally, vertically or diagonally. You only have 3 pieces to play with and move. This means that once you have added your THIRD piece to the grid, your NEXT move actually affects the FIRST piece that you placed. Each X or O you add to the game grid has a handy number next to it. So, when all three of your pieces have been added to the grid, your next move always removes the piece with the number 1 on it.

You have two different game modes to choose from: ‘Challenge Computer’ mode (1 Player), and ‘Pass and Play’ Mode (2 Player). In 1 Player mode, there are 8 different levels of difficulty: Learn, Novice, Easy, Medium, Hard, Very Hard, Almost Impossible, and Impossible. For first time players, we recommend that you play the ‘Learn’ or ‘Novice’ level. In 2 Player mode, you play with a friend or family-member. In both modes, you can choose who moves first – you or your opponent.
