How to play
- Goal
- Divide every cell into connected regions, each with exactly two clues and an area strictly between their values.
- How it ends
- A chart is complete when every region satisfies the rules. Boundaries are editable until completion; Replay starts Practice. There is no loss.
- Record
- Your first unassisted solve of each chart keeps its time; replays are Practice.
- Every cell belongs to one region connected through side neighbours. Draw walls on interior borders to separate regions.
- Each region contains exactly two circled clues. Its area, counted in cells, must be strictly larger than the smaller clue and strictly smaller than the larger clue.
- A 1 and 3 need exactly two cells. Equal clues cannot pair because no area lies strictly between equal numbers.
- Tap a border in Wall mode to toggle a wall. Join mode adds an optional dot marking an open border; join notes are not required to finish.

Tips for Araf
- Separate equal clues Two equal clues can never share a room. A wall must separate neighbouring equal clues.
- Count the available cells A 2 and 4 need a three-cell room. Include both clue cells when counting.
- Keep every room connected Room cells connect through sides; touching only at a corner does not connect them.
Questions about this game
Does the area include both clue cells?
Yes. Count every cell in the room, including both circled clues.
Can a room have three clues?
No. Every room contains exactly two clues.
Must I mark every open border?
No. Join dots are optional reasoning notes.
Does Restart reset the clock?
No. It clears editable boundaries and retains the original clock. Undo can restore the cleared entries.
What happens when I replay?
Replay is untimed Practice and preserves your first finish time. Reloaded unfinished attempts remain local while progress and Undo are retained.
All charts and worked diagrams are original. Progress and Undo save in this browser. Reloaded first finishes and detected clock or browser-suspension discontinuities remain local. Unsafe or unavailable storage is reported in-game. This is an independent implementation of the classic Araf rules.
