DIGIT EXPERIMENT GUIDE
Shape a number and watch its score respond instantly
Number Sandbox turns each digit into a control. Increase or decrease positions, reverse the value, sort its digits, try a random number, and observe how every edit changes its patterns and EP.
Tune individual digits
Each position can cycle through valid values. The first position respects ordinary number formatting, so edits do not create hidden leading zeroes.
Watch traits appear
The score, tier, digit sum, unique-digit count, and earned badge list update together, making cause and effect easy to inspect.
Use the sandbox to learn badge behaviour
Small edits can remove one badge while creating another, and some visible changes leave the total almost unchanged. Working one digit at a time makes it easier to see which structures are sensitive to position, repetition, divisibility, or the overall digit set.
Sandbox is exploratory rather than competitive. A shaped number is not an official daily result, but it can be saved to the journal, shared as a card, or opened in Calculator for a more detailed probability breakdown.
PLAYER QUESTIONS
Useful details before you start
Can the sandbox create 1,000,000?
Yes. The complete supported range includes one million, and the controls keep all edits within that boundary.
Why did several badges change after one digit edit?
Many definitions use the same digits in different ways, so one substitution can affect repetition, sums, divisibility, sequences, and special constants at once.
