XO Elevation

Tic-tac-toe, but the board goes up.

XO Elevation is played on four 4x4 grids stacked in space. A line of four wins, in any direction: along a row, down a column, straight up a pillar, across a diagonal, or corner to corner through the whole cube. There are 76 ways to win and most of them are the ones you did not look at.

Rotate the cube with a drag to read the position, or switch to the layers view to see all four boards side by side.

PLAY THE COMPUTER AT ANY LEVEL
One slider sets the opposition, from an opponent that barely pays attention to one that never misses a win and always blocks yours. Set it where the game is fun, not where it is punishing.

STUCK? ASK
The hint button marks the strongest move on the board, at full strength whatever level you are playing. And if the computer beats you, Save me takes back its winning move so you can answer the threat you walked into.

PLAY A FRIEND
Host a room, share the six-character code, and play from two devices. The server keeps the game honest: it decides whose turn it is and refuses a move that is not legal.

TRACK YOUR GAME
Every finished match goes into your record: win rate, streaks, average length, and the toughest setting you have beaten. Sign in with Google to keep that record under your account, or just play as a guest.

FIVE SOUNDTRACKS
Orbital Drift, Nebula Lullaby, Ion Trail, Deep Field and Starlight Waltz, all in G major, all loopable for as long as you want to keep playing. Music and sound effects have their own switches and volume, and everything goes quiet when the game is not in front.
