The mission takes place in Castle Town, Soleanna. An intelligent mathematician named Aristo gives Sonic a series of five questions, in each of which he must correctly guess how many Containers there are in a stack.
Aristo begins each question by showing the player a stack of Containers, providing time to estimate the number of Containers in that stack. It is recommended to observe them while the game is paused so that the timer does not run. Once the player confirms that they are ready to give an answer, a row of boxes marked with the numbers 1 to 9 appear in the area. The player must run up to the box with the number that correctly answers the question and destroy it. This process is used for all five questions. It can be difficult to judge the Containers hidden out of sight, but the first stack contains four Containers, the second stack contains seven, and the third, fourth and fifth stacks each contain nine. Answering any of the questions incorrectly will force the player to restart from the beginning. The Town Mission is cleared when the player gets every answer correct.
