Three rules, and that's the whole game

It takes about five seconds to learn and a surprisingly long time to master.

  1. 1

    Pick up a tube

    Tap any tube holding liquid. It lifts, ready to pour.

  2. 2

    Pour it into another

    Only onto a matching colour, or into an empty tube. Everything that matches on top goes across at once.

  3. 3

    One colour per tube

    Get every colour into a tube of its own and the board is done.

Built around a solver

Most sorting puzzles shuffle the colours and hope for the best. Decant runs a full search over every board before handing it to you, which makes a handful of things possible that otherwise simply aren't.

Every level is winnable

Boards are dealt at random, then proven solvable before they reach you. If a deal can't be finished it's thrown away and another is tried. That's a proof, not a hope.

Every level has a par

The exact fewest moves a board can be finished in, found by search and never estimated. Match it and you played it perfectly. Three stars means precisely that, and nothing looser.

It tells you when you're stuck

One careless pour can make a board impossible, and most games leave you shuffling for minutes before you notice. Decant checks after every move and says so immediately.

Hints are real advice

Not a canned tip. The solver re-runs on your board exactly as it stands and shows the first move of a genuinely optimal solution, so it stays correct however far off track you've wandered.

Plays without a connection

Puzzles are generated on your phone, not downloaded. No account, no sign-in, no server waiting to go down. Your progress stays with you.

Colour-blind friendly

Switch on symbols and every colour carries its own shape. A game built entirely on telling colours apart should still be playable if you can't. Try it just below.

Every colour has a shape

Around one man in twelve has some form of colour vision deficiency, and ruby against emerald is exactly the pair that disappears. With symbols on, matching stops depending on colour at all. Switch them off to see what the same board looks like without them.

One shared puzzle a day

The Daily Challenge is the same board for every player on earth, and it shifts shape through the week. Keep a streak going if that's your sort of thing.

Questions

Can I get stuck on a level forever?

No. Every board is proven solvable before you see it, undo and restart are free and unlimited, and the game warns you the moment a board can no longer be won.

How many levels are there?

There's no fixed list. Levels are generated from their own number, so level 400 exists and is the same board for everyone. Difficulty climbs steadily for the first few dozen and stays demanding after that.

Does it need an internet connection?

Only to load an ad, which is always your choice. The puzzles themselves are built on your device, so the game works on a plane or underground.

What do ads get used for?

Optional extras only: an additional hint, or skipping a level you've had enough of. Undo and restart are never behind an ad.
