Features

  • Seventy hand-built levels, every one verified solvable by a solver before it ships.
  • Seven districts, walked in order, each its own hour of the night.
  • Tonight’s shift — one extra board posted nightly, the same board for everyone worldwide, derived deterministically from the date. No server, no download, no account.
  • A Game Center leaderboard for the nightly board, reset every night.
  • iCloud sync, so the same city carries across your devices.
  • Fully offline. The game makes no network calls to play.
  • Data Not Collected on the App Store privacy card — no analytics, no crash reporter, no third-party SDK.
  • Accessibility: a high-contrast mode and full respect for Reduce Motion.
  • Complete Turkish localization, not a partial pass — every string, in both languages.
  • No timers, no ads, no accounts, no randomness. Water settles to the same volume-weighted average every time.
