Tap the symbols in order to write the number, then check. Hints show the next decimal place.
How to play
A number appears. Tap the symbols from left to right to write it, then press Check. The tray only has the symbols that make sense for the range, plus one extra.
Stuck? Hint tells you which decimal place comes next and how it is written. Each round has 10 numbers that get longer as you go.
Why build instead of choose
Writing a numeral yourself is harder than picking it from a list. Building it place by place (thousands, hundreds, tens, units) is also how the system works: 2026 is MM + XX + VI.

Common questions
Do hints cost points?
No. The hint only shows the next decimal place. The answer still counts as correct if you finish it.
Can I use the keyboard?
Yes: type the letters, Backspace removes the last symbol and Enter checks.
