Make a spinner (or spinners) that you think could match the mystery spinner.

Your only clue is the graph that shows which colours the mystery spinner landed on.

When you have saved your spinner(s), select Test above.

Test your spinner

Select a saved spinner.

Choose the number of spins and
the speed.

Select Spin. Then look at the
results to see if they match the
mystery spinner's.

Compare your spinner's results to the
mystery spinner's graph.


Try a larger number of spins and see
what happens.

OK

You've now tested this spinner by
spinning it 10 000 times.


Compare the graphs to see if the
results are the same as the mystery
spinner's. To find out if it's a match,
you can select Check spinner.

Check spinner

Sorry, this spinner doesn't match the
mystery spinner either.


Here's a hint. Try to build a spinner
with the same amount of each colour
shown in the results graph for the
mystery spinner.

Oops!

This spinner doesn’t match the
mystery spinner.


Choose another spinner to test, or
select Build to make a new one.

Great! You found the mystery
spinner! The size of each column in
the graph helps you work out how
much of each colour to put on the
spinner. Spinning as many times as
possible gives test results that can be
trusted the most.
