## Description

Cella is a Heyawake puzzle — the name means &quot;divided rooms&quot; — for players who like unhurried, honest logic.<br><br>The grid is cut into rooms, and some rooms carry a number. That number is exactly how many of the room&#39;s cells you fill. Two filled cells never touch side by side. Everything you leave empty forms one single connected area — and no straight line of empty cells may run through more than two rooms. Tap a cell to fill it; press and hold to mark it empty.<br><br>HINTS THAT EXPLAIN<br>The hint button shows the next step the board allows, and tells you which idea it used.<br><br>LEARN IT BY PLAYING IT<br>Heyawake&#39;s last rule is about neither a single cell nor a single room, and no sentence in a rulebook makes it obvious. The walkthrough hands you real positions and asks for the one square that follows, then shows you why. No board in it was made up — each is a genuine puzzle stopped at the moment the idea it teaches becomes the forced next move.<br><br>THREE WAYS TO PLAY, ALL OFFLINE<br>• 12 campaign chapters, from gentle openings to genuine work<br>• A daily puzzle, the same one for every player worldwide, with a gentle Monday and a demanding Sunday<br>• Endless mode in four difficulties: Easy, Medium, Hard, Expert<br><br>MEASURED IN MONTHS, NOT STREAKS<br>Fill in every day of a calendar month and the month earns its own trophy. There is no streak to lose: a day you missed can still be filled in from the archive, so a week away from the game costs you nothing.<br><br>BUILT TO BE PLEASANT<br>• Warm Material 3 design, light and dark, following your system colours<br>• Completely offline — no account, no sign-in, no network needed<br>• Boards shaped for a phone held in one hand<br>• No countdowns you did not ask for and no interruptions<br><br>27 languages supported. No account required. Pure logic.
