Clatter: Ball Sort Puzzle

Clatter is a free ball sort puzzle game. Colored balls roll down a track, you flip the switch below, and every ball drops into the bin matching its color. One tap, one decision, and the next ball is already on its way.

🎯 HOW TO PLAY

A ball rolls down the rail toward a switch
Tap the switch to steer it into the matching bin
Each bin shows how many balls of its color are still coming, so you can plan the run
Three balls in the wrong bin and the run ends
Fifteen seconds to learn, a lot longer to master.

🧠 A COLOR SORT PUZZLE WITH REAL LOGIC
Nothing is hidden or random. You can see what is coming and how much room is left, so every miss is a decision you can learn from, not bad luck. If you like ball sort puzzle games, color sorting games and logic brain games, this one asks a little more of you.

🛤️ 12 MARBLE RUN BOARDS, EACH WITH ITS OWN TWIST

Speed rails and slow rails that change the pace mid-run
A switch that flips itself on a timer, ready or not
A dye rail that repaints a ball on the way down
Two mouths feeding one track, so balls arrive together
A three-way spinner switch with three bins to serve
Six-bin boards, merging rails and side entries
Boards unlock as you climb, and later ones stack these ideas on top of each other until a single run takes your full attention.

🎲 9 WAYS TO PLAY

Journey — the main climb, with stars on every level
Daily — one puzzle a day, the same one for everyone
Endless — keep sorting until three misses

Relay — the track swaps out mid-game

Shuffle — bins trade colors while balls are rolling
Nerve — one life, no tools
Free play — any board, any difficulty

⏪ TWO TOOLS, NO PUNISHMENT
Sent a ball to the wrong bin? Rewind plays the last five seconds backwards, gives the life back, and drops you in exactly where you were. Slow halves the speed of the board when you need a breath.

⬢ EARN AS YOU SORT
Every ball sorted earns Bolts. Spend them on rail styles, board palettes, marble skins and trails, and the whole run changes its look. Bolts come from playing.

✅ NEVER AN UNFAIR LEVEL
Every level is solved by the game before you ever see it. If it cannot be cleared cleanly, it is thrown away and a new one is built. No impossible boards, no luck walls, no level that needs a purchase to pass.

NOTHING INTERRUPTS A RUN
No forced ads. Nothing plays when you lose, nothing plays between levels. The only clips are the ones you choose to watch.

LEVELS THAT NEVER RUN OUT
Levels are generated fresh, so there is always another one waiting and no two runs feel the same. Play a round on a commute, in a queue, or in the two minutes before something starts.
