- Touch screens start in Tap mode: tap the entries in order, and tap one again to take it back.
- Drag mode: drag an entry (press and hold on a phone), or use the arrow buttons.
- Keyboard: space to pick up, arrows to move, space to drop.
- Pause whenever you like (Esc). The board hides while the clock is stopped.
About this quiz
A byte is eight bits. Larger units put a metric prefix in front of the byte, and each step up the list is a thousand times bigger than the one before.
- With SI prefixes a megabyte is exactly 1,000,000 bytes; the binary unit of 1,048,576 bytes is called a mebibyte.
- Ronna and quetta, the two largest prefixes, were only adopted in 2022.
- A gigabyte is 1,000,000,000 bytes, and a gibibyte is 1,073,741,824.

Note on the data. Prefix names and their powers of ten follow the BIPM's table of SI prefixes; the byte of eight bits and the decimal meaning of kilobyte, megabyte and gigabyte follow the NIST page on binary prefixes. Both were checked on 3 October 2026.
