Cipher Key

A digit–symbol coding task in the style of the WAIS Coding subtest

How it works

At the top of the screen is a cipher key: each digit from 1 to 9 is paired with a symbol.

The key

Your task

• A digit appears in the center of the screen.
• Look it up in the key, then tap the matching symbol in the grid below it.
• Work as quickly and accurately as you can. The test runs for 120 seconds.
• The symbols in the answer grid are not in key order — you have to consult the key (until you start memorizing it, which is part of the task).

You'll get a short practice round first, with feedback. During the real run there is no feedback — just keep moving.

Tip: on a keyboard, the number keys 1–9 select grid positions (like a phone keypad: 1-2-3 top row, 4-5-6 middle, 7-8-9 bottom).

This is an informal instructional analogue built for teaching and self-exploration. It is not the WAIS, uses no WAIS items or norms, and produces no clinical scores.

Informal instructional analogue. Raw score here means digits correctly coded in 120 seconds. Scores are for reflection and discussion of processing speed, incidental learning, and sustained attention — not diagnosis.
