■ Stability improvements Under-the-hood work to keep the app running smoothly.

■ Pick up where the web left off Get a 6-digit code on the web, enter it in the app, and your whole run comes with you. ■ A gentler start Board sizes now grow more evenly, you can choose how to begin, and no full-screen ads appear in the early levels. ■ Room alerts for everyone playing Record alerts used to reach only the room's host — now everyone competing gets them. ■ Notifications open the right screen Midday takes you to a new stage, evening to Today's League.

■ Watch an ad for a helper Out of hints or reveals? Watch a short ad to top up right away. Earning them with seeds works exactly as before. ■ Many more puzzles A large batch of new stages, including 40 boards that break out of the plain square for the first time. ■ A clearer board Cells now carry a soft bevel, so colour regions read at a glance.

■ A brand-new tutorial Six dedicated puzzles teach six solving techniques, one at a time. Revisit any of them from the "Techniques" tab in Help. ■ Music that fits the screen Lobby, puzzle and league each have their own track now. The starting countdown adds a tone and a short buzz. ■ Rules always in view Match, league and daily screens keep a rules summary on screen, plus a one-time walkthrough when you start.

Hints got a lot more helpful in this update. ■ Hints now come in three steps First where to look, then which rule applies, then what you can rule out. Instead of handing you the answer, the hint walks you through the reasoning. ■ The board has row and column numbers No more "over here" — hints can now point to "row 3, column 5". ■ A cleaner hint view Only the cells that matter stay lit: the evidence and the conclusion. The X marks you already placed step back out of the way. ■ One name, everywhere Set your name once in Settings and it shows up the same across leagues and matches. You can now clear it, too. ■ Sound is here Soft marimba effects when you place a spirit, plus a calm background track. Both can be turned off in Settings. ■ Also Shared links now open straight in the app, and we fixed a sign-in issue that could leave you stuck.
