Tic Tac Toe Bid War

Win squares by outbidding your rival. Where you play matters less than how much you are willing to pay.

Two careful players draw at tic tac toe every time. So we went ahead and put the squares up for auction.

Each turn, one square is up for grabs. Both sides bid points in secret, and the higher bid takes it. Three in a row wins.

THIRTY POINTS, AND THAT IS ALL

They never go up. The loser pays too. Bid 12 on the centre and you have 18 left for the rest of the game. Hold back and your rival quietly lines up three.

MATCH THE BID AND NOBODY TAKES IT

The square stays empty. Only the points are gone.

WAYS TO PLAY

• Solo: Easy, Normal, Hard, Ultimate
• Two on one device: the screen hides each bid
• Online: random match, or a passphrase for a friend

TWO MINUTES A MATCH

Five seconds to pick a square, five to name your price.

RANKS AND STREAKS

Random match results move your rank. Sixteen of them, 10 kyu up to Master.

How much will they throw at the centre? How far is it worth going to block a line? Is this one worth giving up for the next? Nine squares, and never the same game twice.

So. What is this one worth to you?
