Description by OT Games Written by the developer, not by AppBrain. Click to read.
One Second Hero is a fast reflex and brain game that tests your reaction time and your focus at the same time. An instruction appears: "Tap BLUE", "Swipe UP", "DON'T TOUCH!"… Do the right thing before the timer bar runs out. Sounds easy? The time gets shorter as your score climbs, and the instructions start trying to trick you.
HOW TO PLAY
• Read the instruction and do it before time runs out.
• Every mistake or late answer costs a life. You have 3.
• Get 15 right in a row to earn a life back.
• When the game ends, you can watch an ad to continue with +1 life.
27 DIFFERENT TASKS, ALL FREE
Tasks unlock as you play, not as you pay. No paywall, no subscription, no locked modes.
• Colors and shapes: tap the right color or shape, find the biggest, spot the odd one out. Watch out for traps like "Anything but PURPLE"!
• Numbers: pick the bigger, odd or even number, solve the sum, count the dots, find the missing number.
• Reflexes: swipe, swipe the opposite way, press and hold, double tap, tap in order, catch the runaway ball, tap when it turns green.
• Focus and memory: tap the ink color (a Stroop test), remember the color, keep your eye on the ball under the cups.
You get extra time the first time you meet a new task.
