Notes 



Click 'start' to see the starting number, and then follow the instructions, one at a time, until you reach the end. Not everyone can solve every 30 Seconds puzzle within 30 seconds.

I have deliberately chosen not include the answers – you can use a calculator to see the value at each stage of the calculation.

Note: take a look at the information about the difficulty levels.

All daily items change at midnight GMT – set your local time zone.

Note: BrainBashers has a Dark Mode option – I recommend not using your browser's dark mode or extensions for BrainBashers
