चार की पंक्ति 7×6 गुरुत्व बोर्ड का क्लासिक खेल है: गोटियाँ गिराएँ और क्षैतिज, ऊर्ध्वाधर या तिरछी चार गोटियाँ जोड़ें।
Every disc changes both the visible threat and the future landing height of a column. A strong move creates a line while limiting the opponent's reply.
The direct Battle loop keeps the board readable from the first drop to the Result. Replay resets the board so a different opening can be tested immediately.
The board has seven columns and six rows. A disc falls to the lowest open cell in its selected column; a full column cannot accept another disc.
A round ends when a player connects four discs horizontally, vertically, or diagonally, or when the board fills. Difficulty changes the AI response, not the win rule.
Hint highlights one tactical suggestion without auto-playing it; Undo restores the prior turn. Result offers Replay and Main, while local settings stay in this browser.
Easy, Medium, and Hard change the opponent's decision pressure while keeping the same 7x6 board and four-line win condition.
Replayable rounds make progress visible through better openings, safer blocks, and fewer forced replies rather than account levels.
Four in a Row uses the shared Classic Logic Lab shell, a responsive 7x6 gravity board, AI-turn lock, advisory Hint, reversible Undo, Result recovery, and browser-local preferences.
