Buzzer Knockout vs BlindSec

Stop the timer at exactly 10.00 seconds – without looking. Buzzer Knockout turns the stopwatch challenge into a party game. Everyone sees the same target time, say 6.7 seconds. Hit the buzzer to start an invisible timer and hit it again when you think the time is up. Closest to the target wins. No display, just your sense of timing.

Party games for friends: find out who has the fastest reaction time. Hit a target time without seeing a clock, then reveal everyone's results. One phone for the whole group — or a screen each. MADE FOR GETTING TOGETHER Play solo, against the computer or with friends, depending on the game. Up to 12 people can share one phone in the timing game. In supported games, invite friends through Messages and play over FaceTime with SharePlay or nearby. Computer opponents are clearly labeled. TIMING, REACTIONS AND MEMORY • Timing game — feel when the target time has passed. Group results stay hidden until the end, then appear from last place to first. • All at once — the same target, separate phones and a shared start. • Reaction — tap when the color changes. Every millisecond counts; watch out for false starts. • Training — Sudden death, Arithmetic, Rhythm and From memory (Easy / Medium / Hard / Survival). Pick a level and test your accuracy. • Mind — Echo, Mosaic, Shape in the air and Colour or word: sequences, patterns, shapes and attention. A MOMENT FOR YOUR MIND • IQ test — around 15–20 minutes of tasks, with an estimated score, uncertainty range, ability profile and response-time analysis. An estimate, not a diagnosis or a professional IQ assessment. • Calm zone — solve nonograms in Picture by numbers or try the Daily challenge. PUT YOUR PHONE IN MOTION • Air charades — draw in the air with your phone while friends guess. • Delayed drawing — try drawing with a camera view that arrives a moment late. • How many centimetres? — estimate a length and compare it with an AR measurement. • Treasure in the room — hide virtual treasure in a scanned room. AR games need a compatible device and camera access. Room scanning availability depends on your hardware. YOUR PROGRESS Achievements, badges, statistics, result history and Game Center leaderboards give you reasons to beat your own best. ADS AND OPTIONAL SUPPORT Every game and feature is available without a purchase. An announced ad break may follow a finished game. Ads do not interrupt rounds. Optional rewarded ads can offer a hint or a second chance. Three ads appear before your IQ result; this is explained before you start the test. Supporters see their result without ads.
