Description
Adds hints and automatic solving to Akari puzzles, and lets you play puzzles from Daily Akari and puzz.link on either site Akari Solver adds solving tools to Akari (Light Up) puzzles on dailyakari.com and puzz.link. 💡 Next move — overlays the cheapest next move a human could logically derive, ranked by a level hierarchy: direct deduction, named solving techniques, depth-1 hypothesis, depth-2 hypothesis, and full search. A ⁉ marker shows where assuming the opposite leads to a contradiction and in how many moves. Press the button again to enter the suggested move. ✨ Solve — reads the board and enters the complete solution. 🔍 Uniqueness check — reports whether the puzzle has exactly one solution. Only 💡 shows at rest; hovering it slides out ✨ and 🔍. When the board is in an unsolvable state, wrong lights and marks are highlighted in red and the contradiction cell is marked with ⁉. On puzz.link, an optional setting shows each clue as the number of lights still to place, Daily Akari style: the numbers count down in the lit-cell color, and clicking next to a used-up clue places a dot instead of a light. A button opens the current puzzle on the other site (Daily Akari ⇄ puzz.link), and any puzz.link Akari board can be played on Daily Akari by putting its akari/... data in the URL fragment. The UI is available in English and Japanese. The extension works entirely inside your browser: no account, no tracking, no data collection, and no remote code. # Changelog ## [0.4.0] - 2026-08-22 ### Added - Add a remaining-lights display mode to puzz.link ## [0.3.1] - 2026-08-16 ### Changed - Speed up exact solving with frontier ZDD - Reuse solution witnesses across hints ### Fixed - Stabilize the hint action controls ## [0.3.0] - 2026-08-16 ### Added - Show the ⁉ badge when the conflict is the hint cell itself - Add uniqueness check and slide-out button row ### Changed - Retake screenshots for the slide-out button row ### Fixed - Fix the fragment Home button being disabled or missing ## [0.2.0] - 2026-08-15 ### Added - Support puzz.link editor pages by accepting bare ?akari/?lightup URLs ### Changed - Play puzz.link puzzles on Daily Akari ## [0.1.2] - 2026-08-07 ### Fixed - Fix daily puzzle fetch by sending timezone via X-Tz-Offset ## [0.1.1] - 2026-08-04 ### Added - Show the cells that justify a technique hint ## [0.1.0] - 2026-07-27 ### Added - Add extension icons ### Changed - Prove marks by depth-2 witnesses so hints keep their ⁉ context - Keep stacking depth-2 marks while a depth-2 light is too hard - Highlight the target lights of a chain mark hint
