4D Tic-Tac-Toe Take turns claiming squares. Four in a row wins, along any straight line through any of the four dimensions. 4D Connect Four Drop tokens into columns; each falls to the bottom of its small board. Four in a row wins, in any direction. 4D Atoms Add atoms to your squares. A full square explodes into its neighbours, in all four dimensions, and captures them. The last player with atoms wins. 4D Reversi Trap a line of other players' pieces between two of yours and they all flip to you, along any of up to 80 directions. Most pieces at the end wins. 4D Light Cycles Steer your cycle one step at a time, leaving a wall behind it. Box the others in, and escape through Z and W when they try it on you. The last one moving wins. 4D Domineering Take turns placing dominoes, each player along their own directions. In 4D you might own X and Z while your opponent has Y and W. Whoever can't place a domino is out. 4D Dots and Boxes Take turns shading the walls between boxes. Close the last wall around a box, cube or tesseract and it's yours, and you go again. Most boxes wins.

4D Tic-Tac-Toe

Take turns claiming squares. Four in a row wins, along any straight line through any of the four dimensions.

Board With 3 or 4 players, tic-tac-toe usually ends in a draw.

How it works

Choose a game, a board, and who plays each seat: friends online, someone beside you, or the computer.
Send each friend their own link. A link is a seat in the game, so send each one to one person only.
Play at your own pace: the page updates by itself, and you can come back to your link hours or days later.

Reading a 4D board

A 4D board is drawn as a grid of small boards. Inside each small board you move in X (across) and Y (down). Moving to the next small board across the grid is a step in Z, and to the next one down is a step in W; each small board is labelled with its Z,W position. So the same square on neighbouring small boards is one step apart, just like neighbouring squares.

Our other games include 4D Builder, Tesseract 261 and Atoms 3D.
