Drop Four — The Classic Connect Four Game with Real AI

Drop Four is a free browser recreation of the timeless Connect Four game, featuring a genuine alpha-beta search AI, three play modes, and support for eight languages. Drop discs into a 7×6 grid, stack them under gravity, and race to connect four in a row before your opponent does.

How It Works

Players alternate dropping colored discs into one of seven columns. Discs fall under gravity and stack from the bottom up. Connect four discs in a row — horizontally, vertically, or diagonally — to win. If the board fills completely with no winner, the game ends in a draw.

A hover preview shows your disc bobbing above the column before you commit, and every drop animates realistically falling into place. When a winning connection is made, the four winning cells pulse with a glowing white ring.

Three Game Modes

  • Player vs AI — take on a genuine alpha-beta search engine with three difficulty levels. Easy plays randomly, Medium searches five moves deep, and Hard searches eleven moves deep — strong enough to beat most casual players
  • Player vs Player — two players face off on the same device
  • AI vs AI — watch the engine play itself, also used as a live demo mode

Key Features

  • Real AI opponent — genuine alpha-beta search, not a scripted bot
  • 3 difficulty levels — from beginner-friendly to genuinely challenging
  • Undo function — reverse two moves in AI mode so you never hand over a free turn
  • Live AI thinking indicator — see search progress percentage during Hard-mode calculations
  • Animated disc drops — smooth falling animation with a hover preview before committing
  • 8 supported languages — English, Spanish, French, Portuguese, German, Japanese, Chinese, and Hindi
  • Classic blue board design — vivid red and amber-yellow discs with a glossy highlight finish
  • Free to play — no download or account needed

Who Is It For?

Drop Four is for anyone who loves classic strategy games, whether playing solo against a real AI, competing with a friend on the same device, or just watching two AIs battle it out. The genuine search-based AI gives Hard mode real teeth, making it satisfying for both casual players and those looking for an actual challenge.
