AqueTurn

Water has not run through this aqueduct in a long time. The conduits are still there, laid into the stone — they have just been knocked out of true. Turn them back, and the fountains come alive.
AqueTurn is a pipe-connect puzzle with one control: tap a conduit and it rotates a quarter turn. Water leaves the brass cistern and travels only where two open ends meet, so a single wrong elbow leaves half a board dry. Wet pipe glows. Dry pipe does not. That is the whole language of the game, and you learn it in about ten seconds.
THIRTY STAGES, FOUR REACHES
Start in the Spring Basin on a five-by-five floor with two fountains to feed. Work up through the Copper Channel and the Saltmarsh Span to the Highfall Aqueduct, eight squares across with seven mouths waiting. Every stage carries a par — the number of turns it takes to put the whole run back the way it was laid — and finishing at or under it takes three stars.
BOARDS THAT ARE ALWAYS FAIR
Every layout is grown as a connected network across the entire grid, then knocked out of alignment. Nothing is random about whether it can be solved: the arrangement you are looking for is the one the generator started from. There is no stage in the campaign that cannot be finished, and no dead square to waste your time on.
THREE THINGS TO SPEND ON MID-RUN
Probe snaps one still-wrong conduit into place and pins it there.
Rollback reverses your last three taps and takes those turns off the counter with them.
Surge lights the finished route for a moment, so you can see where you went wrong.
FOUR TRAINING TRACKS THAT STAY WITH YOU
Spend credits in the training yard on upgrades that persist: open every run already holding a Probe, keep a Rollback in reserve, take a heavier payout from every clear, or buy yourself room over par before the stars start dropping. Four tracks, four tiers each.
BUILT TO RESPECT YOU
Completely offline. No account, no sign-in, no network, no ads.
No timers and no lives to wait out. A board will sit there as long as you want to think.
A daily draw for showing up, with a live countdown to the next one.
Shape marks for players who cannot lean on the outlines, a calm-flow mode that stops the animation, and an option to hide par entirely.
Your stage is saved mid-run, so an interrupted board is exactly where you left it.
Twelve honours mapped to the campaign itself, not bolted on.
Turn the conduits. Feed the fountains.
