Ages 8-20 · Selective focus
Signal Sort is a short practice game for ages 8-20. It trains selective focus and gives you a quick way to work on attention, recall, or reasoning without a sign-up.
Find the target while ignoring distractions. The game trains selective focus in a way that is quick to repeat and easy to measure.
It is built for short sessions, so it works well as a warm-up, a study break, or a reset between heavier tasks.
