Number Chain is a speed test game that challenges your visual scanning abilities and reaction speed. Tap numbers in order from 1 to 25 as quickly as possible - testing your focus, hand-eye coordination, and number recognition.
Average players complete the challenge in 30-45 seconds. Good players finish in 20-30 seconds. Elite scores are under 15 seconds. The key is developing an efficient scanning pattern and minimizing hand movement between taps.
Fun Fact: This type of number sequence test is used in cognitive assessments to measure processing speed and visual attention. It's similar to the Trail Making Test used by neuropsychologists.
