Most of the achievements unlock easily by just completing the game and finding all the gags, it takes about 6 - 8 hours.

You will find down below each stage-chapter and what achievements you can unlock there, that and the picture of the achievement should be enough info in most cases to unlock each achievement to get the desired 100%.
Some are not so clear and for these achievements i wrote some info as spoiler text.
Let me know if you want me to add more info to a specific achievement.

I recommend to play the game until you have found all gags and then go for a clean up, after playing through all stages you can use "Endless Mode" to play through each of the rounds where you haven't got 100% yet, so you don't have to go through each round individually if you missed something.
But however you wanna do it, this guide will help you.

At the end of the guide i posted a youtube video to a pretty useful walkthrough, use it for extra guidance if you are stuck on a stage.



If you are having trouble unlocking any achievement, please let me know and i will try to provide some info and write it down aswell in this guide.

Also if you stumble across any incorrect information in this guide, please let me also know and also also if you have some useful information for this guide, i will gladly add it and credit you.
