3-Sec Quiz: Speed Quiz

Think quick. Tap faster.

3-Sec Quiz is a true-or-false game that gives you just three seconds per question. Tap O for true or X for false. The rules are simple, but every choice counts as your streak grows.

■ Three seconds to decide
Read the statement and choose your answer before time runs out. A correct answer takes you straight to the next question. A wrong answer or an expired timer ends your run.

■ Take on 333 questions
Questions are shuffled for every run. Keep your streak going and see how far you can get—or take on the challenge of answering all 333.

■ Beat your personal best
Check your correct answers, total time, and average time per correct answer. Your best runs are saved on your device, giving you a new target for the next round.

■ Save your results
Turn a memorable result into an image you can keep.

■ Play in English or Korean
Switch languages in the app to change both the interface and the questions.

Starting a run uses one heart, and hearts recharge over time. You can also watch an ad to refill your hearts or continue a run that ended with a wrong answer.
