You will be given a random selection of Roman numerals.
The computer will then display numbers in English one by one.
It's your job to translate the English numbers into Roman numerals. If you see a number that is on one of your blocks, click to select it.
You'll be playing against the computer to see who can tick off all of their numbers first, so the number won't always appear on your blocks.
Read the numeral guide to help you identify them correctly.

XX
Numerals only use seven different letters.
Here are some examples of how to add Roman numerals together:
2 = II which is just two ones combined (1 + 1 = 2).
12 = XII which is X + II (10 + 1 + 1 = 12).
27 = XXVII which is XX + V + II (10 + 10 + 5 + 1 + 1 = 27).
Roman numerals are usually written largest to smallest from left to right, and then added together. However this is not always the case. The Romans didn't like four of the same letter in a row so they developed a system of subtraction.
I can be placed before V (5) and X (10) to make 4 and 9.
X can be placed before L (50) and C (100) to make 40 and 90.
C can be placed before D (500) and M (1000) to make 400 and 900.
For example:
4 = IV the smaller I appears before V so subtract 1 from 5.
9 = IX the smaller I appears before X so subtract 1 from 10.
90 = XC the smaller X appears before C so subtract 10 from 100.
