Conduit: Lost Signals
Logic circuit puzzles
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
A logic puzzle: route the signal. Three dailies, unique to you. No timers, no lives. Miss a day and nothing is taken away.
A logic puzzle: route the signal from Source to Target.
That is the only goal in Conduit — every puzzle, from the first to the last.
What changes is never the objective; it is the mechanisms on the board and the
way they interact. So you are never puzzling over what the game wants. You are
puzzling over how to do it.
A CLEAN, DELIBERATE PUZZLE GAME
No timers. No lives. No energy meters. No fail state. An unsolved board simply
sits there while you think. The only pressure is the one you bring.
DIFFICULTY THAT COMES FROM THINKING
Every puzzle is a genuine deduction with an exact-fit set of pieces — you get
precisely the tiles a solution needs, and no spares. Difficulty comes from
combinatorial depth, never from reflexes, precision, or hidden information.
Everything you need to solve a board is on screen at once.
SIX EPICS, EACH A NEW KIND OF REASONING
· First Light — directional conduits. Which path connects Source to Target?
· Split Signal — splitters, mergers and mirrors. Route to several places at once.
· Switches & Gates — gates and triggers. What has to happen before this is possible?
· Colors & Filters — colored signals, filters and recolorers. Get the right signal there.
· Time & Delay — delay tiles and timing windows. What order do things arrive in?
· Light & Spectrum — prisms and focusing lenses. Split white light, route each colour, make it whole again.
Mechanics are never taken away. Later puzzles combine everything you have
learned, so the game gets deeper without ever getting more cluttered.
A DAILY PUZZLE FOR YOU, EVERY DAY
Three daily puzzles — Easy, Medium and Hard — free and ad-free, unique to
you. They unlock after the first chapter so they are ready when you are.
Keep a streak if you like; miss a day and you lose nothing but the counter.
FAIR BY DESIGN
Nothing you can buy makes a puzzle easier to think through. There is no
pay-to-skip, no solution for sale, no advantage over anyone else. Purchases
unlock more puzzles and cosmetics — never power, never answers.
PLAYS ENTIRELY OFFLINE
No account. No sign-up. No internet connection required. Your progress is
stored on your device and nowhere else.
