Nexora: Signal Isles

The beacons went dark. You’re the Signal Keeper who has to turn them back on.

Nexora is a puzzle adventure set on a chain of floating islands at night. You travel from isle to isle, fix the mechanisms that died out, and watch energy crawl back across the map as you go. It isn’t a quiz app with a story glued on. Each island has its own kind of logic, and later levels start mixing what you already learned.

There are eight islands and 72 levels:

Copper Cay Echo Reef Glyph Mesa Balance Hollow Orbit Marsh Mirror Summit Bloom Grid Crown of Signals

You’ll rotate copper pipes so current actually reaches a receiver, replay stone sequences, drop numbers into unfinished equations, balance floating wells, spot the satellite that breaks the rule, program a twin that mirrors left and right, grow a lattice from row and column clues, and open gates that can all be true at once. The last island pulls those ideas together.

Progress is simple. Finish a puzzle and you earn a Signal Core. Beat the target time or keep mistakes low and you can earn more, up to three. A hint caps you at two. Your best score is kept. Six levels on an island opens the next one. All nine repair that island’s beacon.

The whole game lives on your phone. No account, no ads, no subscriptions, no tracking. Your journey saves locally, so you can put it down and pick it up later without losing anything.

If you like slow, thoughtful puzzles with a bit of atmosphere, this is for you. Restore the lost signals. The isles are waiting.
