This is a game where you challenge yourself to see how many times in a row you can guess the correct answer with a probability of 1/2. Please choose one from the two options "L" and "R". If you answer correctly, the probability of consecutive correct answers at that point will be displayed. You can redo your selection only once during a series of correct answers. *If you try again, the correct answer choices will be drawn again. We plan to continue updating and adding features in the future.
