About this game
This is a quick mental maths workout aimed at older students and adults. You will see a mix of everyday questions across arithmetic, percentages, rounding and squares. Each one has four options and you have up to thirty seconds to pick an answer. There are no penalties for mistakes. You score a point for each correct answer and move on immediately whether you get it right or wrong.
Your high score is saved in your browser so you can come back and try to beat it. Share your result and challenge friends or colleagues to a run. The best results usually come from staying calm, scanning the options and eliminating the obvious outliers before choosing.
