Welcome to Stack Sorting: the only game where your organizational skills are put to the ultimate test! Your mission, should you choose to accept it, is to play with colorful cylinders like they’re your childhood toys—except this time, your mom isn’t around to yell at you for making a mess.

Just click on the stacks and channel your inner Marie Kondo as you move the topmost cylinder to an empty stack or one that has a matching top cylinder (because, let’s be honest, matching is the secret to happiness).

Choose Easy Mode if you want to feel like a sorting genius with stacks galore and time to spare, or dive into Hard Mode if you’re ready to sweat and question your life choices with fewer stacks. Complete all levels before the timer runs out or risk a lifetime of shame from your fellow stack enthusiasts. Good luck, and may the stacks be ever in your favor!
