Century Maths Challenge

Build and improve on your mental maths skills! Century Maths Challenge is a mental arithmetic and times tables quiz based on a number grid of 1 to 100 for kids and adults alike. Every answer you make is removed from the grid, so it gets easier but the questions get harder.

The easy mode of the ‘classic’ mental arithmetic game offers 4 multiple choice answers, while the easy mode of times tables hides all the squares that cannot be an answer. This leaves 37 squares for 81 possible questions for 2x to 10x times tables. The faster you answer the higher the score, with hard levels giving you less time.
