Read the recall direction

Keep the digits in order, then follow the forward or backward instruction for that run.

Read the direction before the digits

Seen in this order4186
Watch the complete run before typing.

Before selecting Show digits, check the direction. Forward means type the order you see. Backward means type that whole order in reverse, starting with the last digit.

Level 1 uses forward recall. Later levels can use either direction, so check before every run. The digits appear one at a time; the row below is a still example, not how playback looks.

Lesson help

Check the direction before each run; reverse only when backward is requested.

Same digits, two possible instructions

For 4, 1, 8, 6, a forward run asks for 4186. A backward run asks for 6814. Reversal changes the positions; it does not sort the digits from high to low.

There is no time limit for typing. Check your order and use Backspace for a correction. Each digit is scored against the position requested by that run’s direction.

Forward4186Backward6814
Backward starts at the end and works back to the beginning.

Read this run backward

The instruction says backward. You see the digits below, in this order. What do you type once the last digit has been shown?

Seen in this order2947
Instruction: backward.

Try it

For a backward run of 2, 9, 4, 7, what do you type?
