Voltline

Voltline is a calm, brain-bending circuit puzzle. Place wire tiles, rotate them to route power from the source to the target, and slot in the right modifiers so the voltage arriving at the terminal hits the exact number. Part pipe-connection puzzle, part routing-math constraint — and it powers on with a satisfying neon surge the moment you nail it.

No timers. No fail states. Just you, the grid, and that "one more level" pull when the circuit finally lights up.

HOW IT PLAYS

• Connect — drop and rotate wire tiles to build a live path from the glowing source to the target terminal.

• Calculate — spend +N, −N and ×N modifier tiles from a limited stock so the running voltage lands exactly on target. Order matters once multiply shows up.

• Power on — when the path connects AND the number matches, the current sweeps down the wire and the terminal ignites.

FEATURES

• Themed worlds that teach one new idea at a time — connect, add and subtract, pick the right modifiers, branching routes, multiply.

• Infinite puzzles, every one guaranteed solvable — each board is built backwards from a real solution, then verified.

• Star ratings that reward the cleanest, most efficient route, not just any route.

• A hint when you're truly stuck.

• A fresh daily puzzle to keep a streak going.

• 100% offline — no account, no sign-in, no internet required, and no ads interrupting a puzzle.

• Accessibility-first — colorblind-safe labels (never color alone), a reduced-motion mode, large touch targets, and haptics you can switch off.

Made for both quick coffee-break sessions and long "just one more" spirals.

Route the power. Hit the number.
