MEJJI Puzzle: Quick-Wins Vol. 2

MEJJI is a logical and aesthetic puzzle created by Dr. Segun O. Adu. It requires you to fill blank cells so that every number or symbol appears exactly twice in each row, column, and the two main diagonals. Big symbols represent a 2x2 grid containing that symbol in all four cells of the 2x2.

How MEJJI Puzzles Work

• The Goal: Place numbers or symbols in a grid layout so that they do not repeat more than twice.
• The Mechanics: Each symbol must appear exactly twice in every row, column, and on the two main diagonals.
• Regions (Big Symbols): Puzzles feature larger, composite symbols called regions. Each region represents four smaller cells that all share the same symbol or number.
