A new challenge every day, the same one for everyone. Two seconds to think, two seconds of verdict.
Lightning doesn't look for the way out. You build it for it.
Every two seconds a discharge leaves the terminal and runs through a network of engraved relays. It follows one mechanical rule, always the same: straight on, else right, else left, else turn back. You get two seconds to rotate a relay, then two seconds of verdict. Nothing to read, nothing to memorise - you understand it by watching the first bolt leave.
HOW IT PLAYS
Tap a relay to turn it a quarter turn clockwise - like a pipe puzzle, except what flows through the pipes is light, and it has a rule of its own. The bolt will not find the well on its own: it obeys the rule, and the rule is the whole game. Four mechanics bend it without ever breaking it - riveted relays that never turn, one-way chevrons, rotating relays that move on their own at each discharge, and mirrors that swap right and left.
WHAT IS IN IT
Three hundred levels, from a first bolt you cannot miss to boards nine rows deep. A daily challenge, the same one for everyone, with a spoiler-free result you can share. Eleven languages, six of them selectable in the game.
Forty levels are free, enough to understand. The next two hundred and sixty open with a single one-time purchase, once and for all - there is nothing else to buy, ever.
WHAT IS NOT IN IT
No advertising. No account, no sign-up, no e-mail. No data collected, no trackers, no analytics. The game runs entirely offline.
Built for one thumb, in portrait. Every control is at least 44 points, every button is spoken by the screen reader, and the engraving contrast is adjustable from the pause screen - for playing outdoors, in the sun.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
One hundred and seventy-two more levels: the campaign grows from 128 to 300. The peak is no higher, the climb is SPREAD OUT - the rise is now felt chapter by chapter, all the way to nine-row boards. Fixed: some levels could be won by turning a single relay, and a figure could come back unchanged.
