About Color Sort
A colour-sort puzzle — also called a water-sort or bottle-sort puzzle — is a game where liquid sits in layered bottles and the goal is to pour until every bottle holds one colour or none at all. Color Sort is a free version of that puzzle, styled as a cart of bright syrup bottles. Tap a bottle to lift its top colour, then tap another bottle to pour; tap the same bottle again to set it back down without pouring.
Colour only stacks on matching colour, so a bottle with room left can still refuse a pour if its top colour is different — the game simply rejects the move and the source bottle wobbles, with nothing lost. Levels 1 to 8 introduce the rule step by step, starting with 2 colours and climbing to 5, with each bottle holding 3 segments and then 4 from level 7. After level 8 the puzzle keeps going with more colours and fewer spare bottles, and no level cap.

How to play
- Tap Let's pour! to begin, or Continue to reopen your saved level.
- Tap a bottle to lift its top colour.
- Tap another bottle to pour — colour only stacks on matching colour.
- Tap Undo to take back your last move, or add a spare bottle for room.
What it teaches
Each pour forces a small look-ahead: pouring onto the wrong bottle can block a later move, so a child learns to scan the whole cart before committing — real sequencing and planning-ahead. Because Undo has no limit and an illegal pour simply bounces back, there is no penalty for testing a pour and rethinking it, which builds self-correction without fear of losing. It also practises plain sorting and grouping by colour, one pour at a time. When a child has the planning basics, the tap-to-mix puzzle Color Mixer uses colour a different way — building rather than sorting.
Frequently asked questions
What is Color Sort?
A free colour-sort (water-sort) puzzle for kids, styled as bottles of bright syrup on a gola cart. The bottles start with their colours mixed into layers, and the cart always holds one or two more bottles than there are colours — that extra room is what makes sorting possible. The goal is to pour until every bottle is either empty or filled with a single colour. There is no clock and no score, just the puzzle.
How do you play Color Sort?
Tap a bottle that still needs sorting to lift the whole run of matching colour on its top, then tap a second bottle to pour it in — or as much of it as fits. A pour only lands if the destination bottle is empty or already showing the same colour on top; anything else is rejected. Tap the lifted bottle again to set it back down without pouring.
What age is Color Sort for?
Best for ages 5 to 8. The first levels use just 2 colours in 3-segment bottles, small enough for a 5-year-old to track by eye, then widen one idea at a time. From level 7 bottles hold 4 segments and the add-bottle helper doubles, and the later levels crowd the cart with up to 12 colours and a single spare bottle.
Is there a timer or score in Color Sort?
No. Color Sort has no timer, no score, no stars and no lives — a deliberate choice for a planning puzzle, where a clock would push a child to pour fast instead of thinking ahead. Progress is just the level number, saved automatically on the device.
What happens on an illegal pour?
Nothing changes on the board. If the top colours do not match, or the destination bottle is already full, the pour is rejected and the source bottle gives a small wobble to show the move was not allowed. There is no penalty and nothing to undo, since nothing was poured.
What do Undo and the add-bottle button do?
Undo steps back the last thing that happened — a pour, or an added bottle — with no limit on how many times it can be tapped, so a wrong plan costs nothing but a tap back. The add-bottle button drops an extra empty bottle onto the cart for more room: levels 1-6 allow one per attempt, and from level 7 that rises to two; the allowance resets each time the level restarts.
How many levels does Color Sort have?
Color Sort has no fixed end. Levels 1-8 introduce the rule step by step, climbing from 2 colours up to 5 and adding a fourth bottle segment along the way. Past level 8 the climb keeps going, using more colours and fewer spare bottles as the level number rises, up to a ceiling of 12 colours, so there is always a next one.
Is Color Sort free? Any ads or sign-up?
Yes, completely free, with no ads, no account and no sign-up. It runs in any browser, can be added to the home screen, and saves your child's level on the device so play picks up where it left off.
