zenkari
A native Akari (Light Up) puzzle app for iPhone and iPad — place lanterns, light every open cell, and solve logic grids with touch-friendly play and a steady flow of puzzles.
Why it exists
Akari is a classic Nikoli logic puzzle: numbered walls, orthogonal light rays, and no two lanterns shining at each other. zenkari brings that game to iOS with readable grids, haptics, accessibility support, and enough variety to keep daily play interesting.
Highlights
- Classic Akari rules — place lanterns on open cells, satisfy numbered walls, and light the whole board without mutual line-of-sight conflicts.
- Variations — standard play plus modes such as coloured light, mirrors, twins, queens (diagonal rays), regional boards, and hex grids (availability may vary by release).
- Fresh puzzles — procedurally generated boards by difficulty and size, bundled puzzle packs, and import support.
- Daily challenge — a new puzzle each day with a target time (requires Game Center sign-in for leaderboards and challenge tracking).
- Game Center — leaderboards, achievements, and fastest-time previews per board size and variation (optional; core solo play does not require an account).
- Tutorial and helpers — step-by-step how-to-play, optional conflict highlighting, timer, marks, sound, and haptics.
- Accessibility — VoiceOver labels on the grid, Dynamic Type in navigation and settings, Reduce Motion support, and ads kept out of the primary assistive focus order.
- No sign-in for solo play — saved games, settings, and local progress stay on your device.
