About this game

Connect the Dots is a pipe puzzle that fixes the thing everyone hates about
connect-the-dots pipe puzzles.

Drag from a glowing node to its matching pair to lay a pipe between them. Pipes
cannot cross. That is the whole rule.

What makes it a puzzle is the interference. The short route for one pipe runs
straight through where another one has to go, so somebody has to give way, and
working out who is the game.

NO HUNTING FOR THE LAST EMPTY SQUARE

Most games in this genre also demand you fill every cell. So you join all the
pairs, find one square still empty, and go back to unpick finished pipes and
pad them with pointless detours until the gap is gone. That is not solving. It
is upholstery.

This game does not ask you to do that, because it does not have to. Every board
is built so there is exactly ONE way to connect its pairs at all, and that one
way happens to fill the grid. Join the pairs and the board completes itself.

You are never padding. Every turn a pipe makes is forced.

ONE ANSWER, AND WE CHECKED

All 210 boards were verified by an exhaustive solver and kept only if they had
a single answer. Nothing was generated and shipped unverified. That is what
makes the perfect badge worth chasing: solving a level in one drag per pipe,
with no hints, means you found THE answer.

BUILT TO BE READABLE

• Every pair has its own shape as well as its own colour. On the big boards
there are sixteen pipes at once, and colour alone is not enough, and for a
colour-blind player it is not enough at all. Circle, square, diamond,
triangle, cross, and eleven more. You can play this game in greyscale.
• A strip under the board shows which pairs you have left, so you never have to
hunt the board for the one you missed.
• Dark board, bright pipes, nothing flashing.

210 LEVELS, SEVEN PACKS

Ember 5x5, Copper 6x6, Signal 7x7, Lattice 8x8, Cascade 9x9, then two 10x10
packs, from a spacious Aurora to a crowded Zenith. Thirty levels each, growing from three
pipes to sixteen. Later packs open as you work through the earlier ones, and you
never need to finish a pack to move on, so one level you cannot crack will never
wall off the rest.

No timer. No lives. No way to lose. Put it down mid-pipe and it will be exactly
where you left it.

NO NONSENSE

• Undo and restart are always free.
• Ads keep it free: a banner under the board, and a short advert that may play
when you leave a finished level, never in the middle of one and never in your
first few. Every other advert is one you choose to watch, and its button says
AD before you press it.
• In-app purchases are optional and small. Fuses buy the three boosters
(reveal a pipe, clear the crossed pipes, rewind), and a single one-off
purchase removes the banner and the short advert between levels, and makes
the daily gift bigger. Nothing is locked behind a paywall: all 210 boards
stay free, sparks are earned only by playing and buy panel casings and
nothing else, fuses also arrive with the daily gift and every rank, and the
adverts you choose to watch still work exactly as they did for anyone who
would rather not pay.
• No account, no sign-up, no email.
• Plays completely offline. The puzzles are in the app, not on a server.
• No tracking by us. Your progress stays on your device.

Whether you call it numberlink, connect the dots or a pipe puzzle, this is the
version that respects your time.

Free. Good luck with Zenith.
Connect the dots without crossing. 210 pipe puzzles, each with one answer.
