Water Sort: Glassworks

Glassworks is a water sort puzzle where the tubes are different sizes - and
that one change turns a familiar game into a different one.

Tap a tube to lift its top run of one colour, tap another to pour it in. A tube
is finished when it is FULL of one colour. The tubes hold two, four or eight,
and every colour's supply exactly fills one of them.

So the question is no longer "where does this colour go". It is "which colour is
this tube for" - and you have to answer it before you pour anything.

HOW TO PLAY
- Tap a tube to lift its top run of one colour
- Tap another tube to pour it in
- You can pour onto an empty tube, or onto the same colour
- Only as much goes across as fits
- A tube is done when it is full of one colour

WHY THE SIZES CHANGE EVERYTHING
One colour on the board has eight units and belongs in the tall tube. Two of
them have two units and belong in the little vials. So the tall tube is spoken
for before you touch it - and dropping any other colour into it is a perfectly
legal move that quietly costs you the board, because the eight-colour then has
nowhere left to gather. Working out which colour is the big one, before you
commit, is the puzzle.

WHAT YOU GET
- Hundreds of levels, from four tubes up to fifteen
- Tall tubes, bottles and small vials, mixed from level eight onward
- A difficulty cadence you can feel: every 5th level is HARD, every 10th SUPER
HARD, every 50th a DANGEROUS boss board
- Generous undo, because a mis-tap is a slip and not a mistake worth restarting
- A hint that follows the level's own proven solution, so it always works
- A daily challenge: one board, the same for everyone, every day
- Fourteen colour sets, twelve board designs and ten jar styles to unlock
- A level map, to go back for the ones you finished the long way round

EVERY BOARD IS BUILT FROM AN ANSWER
Levels are not scattered and hoped for. Each one is built backwards from a
finished board, so a solution provably exists before you ever see it - and the
hint reads that same proven line rather than guessing.

NO TIMER AND NO LIVES
No clock, no lives, nothing to run out of by waiting. Walk away mid-level and it
is exactly where you left it. The one limit is a generous move budget - five
times the shortest solution found by search, and never under 20 - counted on
screen as you play, so a board that has gone wrong ends instead of stalling.

PLAYS ANYWHERE, ONLINE OR OFF
Works offline with no wifi. Small download. No account, no sign-up, no personal
details asked for. Your progress stays on your own device.

QUESTIONS PEOPLE ASK
Does it work offline? Yes, every level, with no connection at all.
Do I need an account? No. There is no sign-up and nothing to log in to.
Is there a timer? No timer and no lives. There is a move budget - five times the
shortest solution found by search, never under 20 - shown as you play.
Can I lose? By running that budget out, or by pouring a colour somewhere it can
never gather. Undo fixes a bad pour, and the board tells you when nothing legal
is left.
How is this different from other water sort games? The tubes hold two, four or
eight instead of all being the same size.
Is it free? Yes, supported by ads, and there is nothing to buy.

Glassworks is free and supported by ads. You can watch an ad by choice to earn
extra undos and hints, and coins you earn by playing unlock the colours, the
boards and the jars themselves. There is nothing to buy.

Recent changes:
The level map now runs as one continuous road instead of stopping dead every fourteen levels.

The game also tells you when a newer version is on Play, so fixes actually reach you.
