On hitting the “Finish” button, the player is asked to state how many gray circles have been found. Here play was terminated early, and a wrong guess was made. Note that some of the rays are red, meaning that they have been used before, and are therefore not adding to the dose. The dose used so far is reported continuously on the bottom, along with the current number of rays and ray width. A correct guess advances one to the next level of difficulty. Here the image size is 256 x 256 pixels.
