The official rules for Connect 4 dictate a turn-based structure where players alternate dropping their coloured discs into the grid. Because the game is played sequentially, one player will always complete their connection of four before the other player can respond. There is no mechanism within the official rules for a 'simultaneous drop' that would result in a tie through concurrent moves.
Step-by-Step
Step 1: Player 1 selects a colour and drops a disc into a vertical column.
Step 2: The disc falls to the lowest available space in that column.
Step 3: Player 2 selects a colour and drops a disc into a vertical column.
Step 4: The disc falls to the lowest available space in that column.
Step 5: Continue alternating turns until one player achieves a connection of four or the grid is full.
Example Play Situation
Alice is one move away from winning with a vertical line. Bob drops a disc into a different column to block a different threat. On her next turn, Alice drops her final disc into the winning column, completing her line before Bob can take another turn.
