Goal

A row of arrows appears. Tap the direction the middle arrow points — ignore the ones around it. Answer as many rows as you can in 60 seconds.

Levels

• 8 right answers at a level moves you up; 3 misses in a row moves you down.
• Levels 1–2 mark the middle arrow; from level 3 there are 7 arrows and no marker.
• From level 4 the row moves around the card; from level 5 up and down arrows join; from level 6 the other arrows point every which way.
• From level 7, a dot in the middle means hold — don't tap, and the next row comes. At level 8 each row has 1.2 seconds.

Scoring

A right answer earns 1 + the level, plus 1 for every 5 in a row (up to +3). A wrong answer costs 2 + the level and half a second. Running out of time on a row costs only your streak.

Filtering Distraction

The flanker task measures how well you can keep attention on one thing while similar things right beside it pull the other way — reading in a noisy room, driving past signs, working with notifications around.

Response Control

Hold rows train you to stop an answer that's already on its way — the same brake that keeps you from acting on impulse.
