GridXO - Tic Tac Toe & Gomoku
XO Board Game vs AI & Friend
Free · Designed for iPad. Not verified for macOS.
GridXO is a clean, fast tic tac toe game where every match is a full board of strategy. Play the classic 3x3, or size up to 4x4, 5x5 and 6x6 grids where you need a whole line to win.
Pass the phone to a friend for local 2 player matches, or take on an AI opponent with five difficulty levels from Easy to Expert. No account, no timers, no internet needed.
FOUR GRID SIZES
SMALL 3x3, MEDIUM 4x4, LARGE 5x5 and HUGE 6x6. The bigger the grid, the longer the line you need: 3, 4, 5 or 6 marks in a row, across, down or diagonally.
PLAY WITH A FRIEND
Two players, one device. Pass and play noughts and crosses with X and O, with a running score kept between rounds.
FIVE AI LEVELS
Easy plays loose and forgiving. Normal blocks your obvious wins. Medium spots forks and open threes. Hard searches deep. Expert plays close to perfect, so beat it if you can.
LARGE MAP: 5 IN A ROW
On the 5 in a row and 6 in a row modes you can switch to a big pannable board and hunt your line across a much wider grid, gomoku style.
BUILT TO BE SIMPLE
Tap a cell to place your mark. Undo takes back a move mid round. One tap starts the next round. Sound and vibration can be turned off any time.
PLAY ANYWHERE OFFLINE
No sign up, no wifi, no waiting. GridXO works on a plane, on the bus, or anywhere you have a spare minute.
If you like tic tac toe, noughts and crosses, gomoku or quick two player board games, GridXO is your next match.
X goes first. Line them up.
