## Dr Evil's Math Challenge Game Description
Think Sudoku, but with arithmetic and a whole lot of disco. Welcome to Dr Evil's Math Lab.

Fill every 3x3 house so all nine cells add up to exactly 10. Sounds simple? Try it with 25 houses on the board and column targets breathing down your neck.

Dr Evil's Math Challenge is a number puzzle game wrapped in a 1970s game show theme—complete with a disco funk soundtrack, a theatrical mad-scientist host, and enough groovy style to make your calculator jealous.

WHAT'S INCLUDED
