How to complete Riddle School 3 - Walkthrough Guide
Leaving the classroom
You will need to pick up the ruler from the desk as the game begins. Next, click the globe a couple of times until you see pink gum. Combine them both and throw them into the vent behind the teacher; you will get a rubber band. Throw the rubber band into the teacher's face; you will knock his glasses off. Pick up his glasses and leave the room.
Collecting pennies
You will find the first penny on the floor outside the classroom you just left. Go left and pick up the penny outside the women's room. Go down the stairs in the hallway to find another penny. Go back up the stairs, then go left to find a penny outside Mr. Flask's room. The last penny will be on the rightmost side of the upper floor, under the carrot poster.

Finding the quarter
Go into the men's room, then use the toilet paper in the stall and the flusher to clog up the toilet. The janitor will come by to fix it, so you can head to his closet on the upper floor to pick up a quarter under his chair.
Collecting nickels
Open the first yellow locker on the upper floor, in the rightmost corner, to find five cents inside it.
Talk to Richy, who you will find locked in the closet on the upper floor. Once you're done talking, head to the teacher's lounge and talk to the teacher. Select He's stuck in his locker, His combination is in your class, then click Yes. After the teachers leave, click on the middle drawer to find five cents.
Richy's quarter
Go to Mrs. Oddverb's classroom and pick up the locker password from her desk. The code is 53788078, but upside-down. Head back to Richy and free him.
Then, head to the library and give the glasses to Mr. Read, who will give you a bookmark. Stick the bookmark to the gum on the scale and take it to the supply closet, where you'll use it to reach the top shelf for a dime.
Keyboard key
Go to Miss Count's room and pick up the keyboard key in the pile of monkey dolls. Go to Miss Flask's room and insert the keyboard key into the machine next to the blackboard to retrieve a button. Head back to Mrs. Oddverb's class and give Richy the button to get another quarter.
Escaping school
Go to the cafeteria and get a pudding now that you have a dollar. Give the pudding to Chubb, who will leave the door to the office. Talk to Mr. Mooses and click, I was sent here to see Mr. Potato, and then I'm awesome. Get the key from Mr. Potato's desk and use it to leave the school.
This is all you have to do to successfully escape from school. Certain events trigger other events during your gameplay. So, to end the game without any issues, it's good practice to follow every step in order.
