Medium Brain Trainer Game
The medium level brain trainer game requires you to be able to hold and perform a larger range of calculations in your head than the easy brain trainer game.Here is a sample puzzle:
This puzzle includes the same range of arithmetic operations as the easy puzzle, but also throws in the occasional mix of percentage based questions and square sums too.
The operations also tend to be harder, for instance larger number sums. Some steps will also be much harder than others; there will be some easier ones and some harder ones randomly through the puzzle.
Don't worry if you find it harder than brain trainer maths challenges you see elsewhere - that's because you have a minute here and often have thirty seconds with other puzzles.
Remember to take a look at the archive over time for a range of medium or moderate brain trainer puzzles that will be added there.
