# Digit Lab

Place value · 30 levels

Arrange the digits and discover the best result.

## How to play

- Tap a digit ball, then a digit slot to drop it in. Tap a filled slot to take its ball back.
- × machines need the biggest product. − machines need the smallest difference.
- Filling every digit slot checks your result. The machine says if a better arrangement exists. From level 12 checks are limited!

Big digits belong in big places, but which number gets the biggest digit? In 2-digit × 2-digit, 96 × 87 beats 97 × 86. For a small difference, make the front digits close, then fight with the rest. No number may start with 0.
