Why it sometimes doesn’t look right
Different display styles
Modern phone calculators use smooth fonts, not always classic segmented numerals. The trick is clearer on basic digital calculators.
Orientation issues
You need a full upside-down flip (180°), not a sideways turn.
Character limits
Only certain letters can be represented well with digits. That’s why the tool above warns you if a letter cannot be mapped cleanly.
