Line up four of your discs in a row, column, or diagonal. The first player to do that wins.

On your turn, choose a column. The disc falls to the lowest open space. Keys 1 through 7 drop in those columns.

The player chosen before the match drops first. In a two-player sitting, each new game swaps who drops first. Against Tamaki on this device, that opening choice stays for the sitting. Two on this device share one board, so pass it after each drop. Each player uses the checker color chosen before the match.

Host a table to play someone on another device. Share the 6-character code. The host chooses who drops first, then starts when the other player joins. Each new game swaps who drops first. If someone leaves during a match, Tamaki takes that seat and the game continues.

A full board with no four in a row is a draw. New game clears the board and keeps the score for this sitting. Home ends the sitting.
