About IllusionResistance
Illusion Resistance is a quick optical-illusion test game you can finish in 30–60 seconds. Solve a sequence of visual challenges, answer with 2 or 3 choices, and get instant feedback. Your score combines accuracy and reaction time, and results show category-by-category weakness. Includes three core illusion types: brightness/shadow, size/length, and simultaneous contrast. Replay anytime to compare scores and see if your perception improves.
