About

Your reaction time is not fixed. It can be measured, and it can be trained. 10s brings together 11 very short games that test six distinct abilities: speed, decision, perception, precision, control and memory. A round lasts seconds. The urge to try again lasts a lot longer. WHAT YOU TRAIN • Speed — wait for the signal, stop the clock at the right instant • Decision — left or right, go or no-go, under pressure • Perception — spot the break, use your peripheral vision • Precision — hit moving targets, judge the right moment • Control — ignore the feints, resist the interference • Memory — hold sequences that keep getting longer THREE TIERS THAT GENUINELY CHANGE THE GAME Standard, Intense, Expert. Tiers unlock by playing clean. Windows get shorter, zones move, signals multiply and decoys become convincing. An animation shows you exactly what is coming before you start. NUMBERS YOU CAN TRUST Best, average, consistency, error rate under pressure. A progress curve per game and per tier, the spread of your times, and an overall six-axis profile that tells you which ability to pull up. SEVERAL PLAYERS, ONE PHONE Create as many profiles as there are players. Everyone keeps their own records and their own assessment, and the comparison runs axis by axis. OFFLINE, AND WITHOUT AN ACCOUNT 10s works with no connection and keeps your history on your device. The account stays optional: it exists to back up your records so you can find them on another device. Worldwide comparison and the rolling 7-day leaderboard are a separate opt-in you can decline without losing anything. 10s is an indicative training game. It is not a medical device or a certified test, and its results must not be used to make health or safety decisions.

What's New in 10s

2.5.0

August 11, 2026

This release makes difficulty legible and the numbers honest: • a redesigned tier ladder: Standard, Intense and Expert in a single block, with the briefing and an animation showing what is coming; • a locked tier can be previewed before it is unlocked, with the exact requirement; • an overall six-axis profile, each axis measured by what actually belongs to it — memory finally counts how long a series you cleared, not how fast you recalled it; • total time played, per game and per tier; • a reworked home screen built around your score and your progress; • nickname change, once a week, synced; • send a bug report straight from settings; • quieter round feedback and resized play blocks.
