The whole game with a clock, against the computer or a friend you send a link to.
- Vs. computer
- With a friend
Drop your discs into the frame; they fall to the lowest free place. Four in a row, across, down or corner to corner, wins.
Get four of your discs in a row, across, down or corner to corner, before the other side does.
The frame has seven columns of six places. Take turns dropping one disc into a column; it falls to the lowest free place in it. A full column takes no more. A full frame with no four in a row is a draw.
The first game is yours to start, and who goes first swaps every game after, against the computer and with a friend alike (with a friend the first game’s is drawn at random).
Computer sets how well it plays (Medium to start). Easy looks two discs ahead and now and then drops anywhere; Medium looks five ahead; Hard looks as far as it can in about a second, and minds which rows its threats sit on, as the end of the game decides. It is for the next game while one is on.
Send a friend the link (Copy link) and play from two browsers. The score counts both sides’ wins and the draws.
Tap a column to drop your disc (it waits over the column under the pointer). The arrows pick a column and Enter or Space drops; 1 to 7 drop straight into one. Next game, or Enter, starts the next one once a game is over.
A game against the computer is kept in this browser with the score. A friend’s game goes through a small server that checks every disc, and forgets the game a day after the last one.
