LogiSketch

New: try the reverse conjecture on black and white puzzles. Once you have a guess down with question marks, flip your first guess and follow what the opposite leads to. Any cell that comes out the same both ways is proven, and LogiSketch fills it in for you. The Advanced Marks tour has a new chapter that walks you through it. Also in this update: - The Gift Shop now shows how much the Museum Membership saves over buying galleries one at a time. - Auto-play now names each deduction directly, like "Gap too small" or "Only one gap fits", instead of one vague catch-all label. - Gallery cards now show the puzzle title first, with colors, difficulty, and size together on one line. - On iPad, Puzzle Options opens at full height, so every option is in view without scrolling a small panel. - Fixed: on iOS 27, a puzzle small enough to fit on screen sits in the middle again instead of in the top-left corner. - Fixed: on black and white puzzles, pressing and holding the tool button no longer also switches between fill and X-mark when you let go. - Fixed: a purchase, a spent life, or a solve that landed while iCloud sync was running could be undone by that sync. It now sticks.
