Jenny's Math Puzzle

About the game

Picture a crossword where the clues are sums. Some slots on the board sit empty, the numbers you need are waiting in a pile off to the side, and each row and column has to come out right once you're done.

One wrong digit breaks two equations at once, which is where the fun and the swearing both start. Nothing is locked in, so you can pull a number back out and try another spot. Early boards are gentle. Later ones make you slow down and think.

How to play

• Grab a number with your mouse or your finger and drop it into an empty slot.
• Every equation on the board has to be correct, reading across and reading down.
• Wrong spot? Pull the number back out and drop it somewhere else.
• Fill the whole grid with no mismatches to win.
