ShapeCountQuiz is a brief-memory counting challenge. Mixed shapes flash on screen for a short moment, and you must count only the target shape type. After they hide, choose the correct count to score. Wrong answers count as mistakes, and three mistakes end the run. Early rounds show fewer shapes with longer display time, but higher scores pack the field with more clutter and cut the viewing window. Focus on the named target, ignore distractors, and lock the total before answering. Accurate counting under speed and visual noise keeps the endless run alive.
