3 streams · The number to report appears before each stream

Digits appear one at a time and stop without warning. Before each stream, you will see how many final digits to enter. Keep them in the order they appeared.

Help

Digits appear one at a time, and the stream ends without warning.

Before each stream, you are told how many final digits to enter. Keep those digits in the order you saw them.

There is no counter or progress bar because knowing when the stream ends would make the task easier.

Each requested digit in the right position earns 1 point. Each extra digit you enter subtracts 1 point. The score for each stream cannot be below 0.

There are three streams. Ending early shows the streams you checked, but does not add a completed result to statistics.

Digits are shown on screen. This version does not include an audio mode.
