BlindSec: 10 Second Challenge

Stop the stopwatch at exactly 10.00 seconds. Without looking at the clock. That's BlindSec. Tap to start, tap to stop, and only then do you see how far off you were. It sounds easy until you try it at a table full of friends who are all sure they have a clock in their head. It's a game about your sense of time. Let the game pick a random target or set your own: 5 seconds, 10 seconds, 13.37, whatever you like. Play on your own, pass one phone around the group, or train until you hit it to the hundredth. WHAT YOU CAN PLAY • Timing game — stop the clock on the target second. With friends, nobody sees a score until everyone has had a go, then the results are revealed from last place to first. • Reaction — tap the moment the screen changes color. Every millisecond counts. Solo 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. • Training — challenges where the margin for error shrinks with every level. TRAINING Two challenges, each at four levels: Easy, Medium, Hard and Survival. All of them free. Before each round you see the range you need to hit, and the first miss ends the run. • Sudden death — the target grows round after round, until it breaks apart into several stretches timed in one go. • Arithmetic — the target is the answer to a sum you only see for a moment. You do the math while the time is already running. NO CHEATING The clock disappears for the whole round. While you're timing there are no sounds and no separate vibrations to count, and the background moves in a way that gives you no rhythm to follow. It's just you and your sense of time. Timing starts the instant you touch the screen, and results are shown to the hundredth of a second. STATS AND LEADERBOARDS Round history, personal bests, form charts, a Training progress map and badges, all free. Game Center leaderboards are there if you want them.
