Stroop is a free Android game developed by F.10 Tech. It is a fast-paced game that challenges your perception skills. The game is based on the Stroop effect, which measures the reaction time of a task that requires both reading and naming the color of the words.

In Stroop, you will be presented with a series of words, each written in a different color. Your task is to tap on the color of the word, not the word itself. The twist is that the words will sometimes be written in a color that doesn't match its meaning, making it harder to select the correct color. The game gets progressively harder as you move up the levels.

Stroop is a fun and challenging game that will keep you engaged for hours. It's perfect for anyone looking to improve their perception skills or just looking for a quick and entertaining game to play. The game is easy to play and the graphics are simple yet appealing. Overall, Stroop is a great game to have on your Android device.
