Goal

• Line up 4 of your pieces in a row — vertical, horizontal, or diagonal!

Controls

• Start screen: Pick your color (Protein 🥛 red / Banana 🍌 yellow) and difficulty (Easy/Med/Hard)
• Match: Tap a column; piece drops to the lowest open slot

Rules

• 7-column × 6-row board
• Players alternate dropping one piece per turn
• First to align 4 in any direction wins
• If board fills with no 4-in-a-row: draw

Difficulty

• Easy: Random column
• Medium: Win if possible → block opponent win → center preference
• Hard: minimax α-β pruning, depth 4–5 (55ms timeout)

Tips

• Center column is strongest — most directions to build 4
• Stack low pieces to set up a "double threat" — guaranteed win
• Always watch for opponent's 3-in-a-row
