Cross Number: Logic Puzzle

Cross Number is a math crossword puzzle game that's easy to learn and hard to put down. Every level is a grid of interlocking equations with missing numbers — drag the right digits into the empty cells so that every row and column adds up. One wrong tile and the grid won't balance, so think before you drop!

It starts gently with simple addition and subtraction, then ramps up to multiplication, division, and sprawling grids where every equation shares numbers with its neighbors. Decoy tiles are mixed into your tray, so you can't just fill in the blanks — you have to reason your way through.

HOW TO PLAY

• Drag number tiles from your tray into the empty cells
• Watch out — some tiles are decoys that don't belong anywhere
• Complete every equation to solve the puzzle and earn up to 3 stars
