Train your memory.

How much can you hold?

Digits flash one at a time. Hold the sequence in working memory, then reproduce it without a safety net.

How many can you hold?

Remember increasingly long sequences of digits. Group them your way, move forward, then rebuild the entire sequence from memory.

Compress the pattern.

A stream of bits flashes by. Hold it, decode it, and reproduce it before the signal disappears.

Listen. Remember. Rebuild.

Listen to a stream of spoken digits, stop when you are ready, then rebuild the sequence from memory.

Make the connection.

Pair names with abstract symbols, then reconstruct the associations from memory. A small test of encoding and retrieval.

Remember every detail.

Remember shopping items, quantities, and units, then retrieve the details from memory.

See it. Build it again.

A growing spatial pattern lights up across a grid. Remember the exact path and rebuild it from memory.

Same pieces. New rules.

A visual pattern changes under a hidden rule. Infer the transformation and choose what comes next.
