On the Subject of Coffee Beans

Me and the boys at 3 am awake due to B E A N S

This module has 3 coffee beans on it. Some beans will be moving around. To solve the module, you must consume the three beans in the correct order. Eating a bean at the incorrect moment will cause a strike. Note that you cannot see a bean when it has been eaten.

Finding Valid Beans

To find the valid order of eating the beans, follow the steps below. Hovering over a bean will display its index.

  1. Write down the movements of the empty spot. These can be horizontal, vertical or diagonal.
  2. Look at the transformation it turns into when you combine all transformations according to the table below. Order does not matter.
  3. If this transform is diagonal or nothing, eat the first bean. If it is horizontal, eat the second. If it is vertical eat the third.
  4. Now make groups of each move and the next like 12 23 et cetera. Do not include a pair of the last and a movement thereafter as that doesn't exist.
  5. Look up these combinations. If an even amount of pairs result in diagonal or no movement, eat the first of the remaining two beans, otherwise eat the second.
  6. Finally, eat the remaining bean.
