ShapeCount

ShapeCount mixes two shape types into one rapid counting test. Circles and squares flash on screen for a short moment, then disappear, and you enter the total number of shapes you saw. Correct totals score. Wrong answers are mistakes, and three mistakes end the run. Higher scores increase shape count, shorten display time, and mix both forms more aggressively so your eye has to tally under interference. Capture a quick mental sum during the flash, avoid mixing shape identity with quantity, and submit before the input timer ends. It rewards composed counting as visual clutter rises.
