Stack'n Sort: Association Game

Tube sort puzzle - match pictures by category & clear every level!

STACK - SORT - SOLVE.

Welcome to Stack'n Sort: Association Game - a picture sorting puzzle where tube-based mechanic meets clever category logic. Move image tiles between vertical tubes, figure out which pictures belong together, and clear the board one category at a time.

If you enjoy tube sort games, category puzzles, or visual brain teasers, Stack'n Sort delivers a fresh take that's easy to pick up and genuinely fun to master.

► How to play

- Tap to move any image tile from one tube to another
- Group pictures that share the same theme - animals, desserts, fruits, sports, and more
- Fill a tube with one complete category to clear it
- Clear every category to complete the level

Early levels ease you in, but the challenge ramps up fast. Several themes appear, trickier layouts test your planning skills, and some images could fit more than one group. With a limited number of moves per level, thinking ahead is what separates good players from great ones.

► What makes it different

Most matching games rely on speed or simple pair matching. Stack'n Sort works differently - instead of pairing identical items, you sort pictures by what they have in common.

A vertical tube sorting system gives classic sort puzzles a modern twist. Because you're working with pictures instead of words, every puzzle feels more like a visual riddle than a word game. And with a limited number of moves, there's just enough pressure to make you think - without making it stressful.

Every level feels like a small riddle - easy to start, tricky to figure out, and deeply gratifying when everything clicks into place.

► Your pace, your game

No timer ticking down. No rushing. Just you, the puzzle, and a set number of moves to figure it out.

Play a quick level on a break or settle into a longer session when you want to unwind. Stack'n Sort is designed to feel calm without being mindless - every move counts, and that's what makes finishing a level so rewarding.
