Obviously, this guide will have spoilers for the full game of Kindergarten 3. Proceed with caution if you’d like to play the game on your own. You have been warned.

Welcome to your new school for your third day of Kindergarten! This guide will not only explain how to beat every mission in detail, but it also will tell you how to get every single Monstermon and achievement (hidden or not) in the game! I am JokerFactor, I speedrun the Kindergarten series and hold multiple world records throughout the games, and I was also a beta tester for Kindergarten 3! I hope that means I can go into enough detail while still keeping it brief and to-the-point.

Before you read this guide, PLEASE try actually solving the puzzle for yourself. People put a lot of work into this game and to just ruin it by reading some guide would be screwed up. This guide is only really for people who have genuinely no clue where to go from the point they are at. With that being said, here’s the full guide!

So that you aren’t bumbling around trying to figure out who is who as you read the guide, here is a list of characters with pictures attached so you may get acquainted with their appearance.

10 of the 21 achievements are simply achieved by beating each quest (9 main quests + the quest after obtaining all monstermon), the following 11 are unlocked without having beaten a mission.


Finish a Wednesday alive. Can be done by doing a mission or just by wasting your apples.


Find any way to die.


Find any Monstermon.


This can be easily done during the dialogue options of Ms. Lovelett’s first interaction in her mission.


This can be easily done by being sent to the library instead of recess. Best place to do this, in my opinion, is in Carla’s Mission: The Grate Escape.


Use the Gator Nugget on Linda to enter the lab.


You can do this in many places, but easiest is to go up to the roof while climbing the beanstalk in Carla’s Mission: The Grate Escape, then jumping off the diving board.


You can do this during Davey’s Mission. If you talk to Felix and continuously pester to him instead of talking to Cindy, he will eventually give you his dollar.
