Neuron Burst

Neuron Burst is three short games built around one idea: noticing what isn't there. Do it fast, and don't panic.

NUMBER HUNT
Nine cells, one digit missing, the clock running. Find the gap and hit the key. This is selective attention: sweeping past everything you can see to spot the one thing that is absent.

LETTER HUNT
A letter flashes in one cell, then the grid empties. Put it back - the right letter in the right square. In that pause you are moving something from a fading visual impression into working memory, and holding both what it was and where it was.

PAIR HUNT
Two grids at once. One letter gone, one digit gone. Letters and digits are handled by different networks in the brain, so switching between them under time pressure is the exercise: two halves of the job, talking to each other faster.

Every round takes seconds. Your times are saved so you can watch yourself get quicker, with a chart of your recent runs - the clearest sign that the work is paying off is your own curve bending down.

Each game also has a short, plain-language section explaining which parts of attention and memory it draws on, with links to the research if you want to read further.

WHAT IT DOESN'T DO
No account. No sign-in. No analytics, no trackers, no advertising. The games run fully offline and your results are written to your device, never to a server. There is nothing to unlock and nothing to buy afterwards - you pay once.

Available in English, German, French, Dutch, Italian and Turkish. Suitable from about age 3 upwards, and just as useful at 133.
