BlindSec

Stop the stopwatch at exactly 7.00 seconds. Without looking at the clock. That is all of BlindSec. Tap to start, tap to stop — and only then do you find out how far off you were. It sounds trivial until you try it at a table full of people. FOUR GAMES The timing game and Reaction each come in a solo version and a pass-the-phone version for the whole table. • Timing game — stop the clock on the second you were given. With friends nobody sees a score until everyone has finished, and then the results unfold from last place to first. • Reaction — hit the screen when it changes colour. We count the milliseconds. On your own, or in turns with a ranking at the end. • Delayed drawing — you see your own hand from a moment ago. Now try to draw anything at all. • Training — timed challenges. TRAINING Two timed challenges, each at four difficulty levels: Easy, Medium, Hard and Survival — all four free. Before a round you see the range you have to hit. Both ends of it count. • Sudden death — twenty rounds climbing to twenty seconds. Then the target stops growing and starts breaking apart: a round becomes one, two or three stretches timed in a single go, in eight named shapes. • Arithmetic — the target is the result of a sum shown for a moment only. The measurement starts by itself when the sum disappears, so you do the arithmetic while it runs. Every level has its own rule. On Easy it takes three failed rounds to end the attempt. On Hard the average of your last four counts — one mistake passes, two do not. On Survival the first value outside the range ends it. The margin grows with the target, but slower than the target itself — just as human error does. The same level therefore means the same thing in every round. IT CANNOT BE CHEATED The game protects the measurement in several places at once: • The system clock hides for the length of a round. • The background moves in frequencies that cannot be counted — there is nothing to tally instead of seconds. • While measuring there are no sounds and no haptic pulses — individual taps could be counted. Timing starts the moment the system registers your touch, not when the app reacts: tens of milliseconds, enormous in a game like this. RESULTS TO THE HUNDREDTH Times are shown to two decimal places, never deeper: below a hundredth the screen noticing your touch decides, not skill you can train. Equal times are a tie. The two highest grades come from the screen too: one for a hundredth off, one for dead on. STATISTICS AND LEADERBOARDS Round history, records and form charts — free, with nothing trimmed from the past. Separate tabs for the timing game, reaction and training, each in its own unit.

The extended boards are free too: consistency, warm-up, form by time of day, time distributions and an activity calendar. Game Center leaderboards are optional.
