With this version GridLab is no longer just about Sudoku. Kakuro, Hashi and Binary arrive, three logic puzzles with their own rules, their own grid sizes and four difficulty levels. Sudoku, with all its variants, stays free, while Kakuro and Binary unlock with a single purchase and Hashi comes as a gift. PDF and ePub collections now carry your own title and author, an index that takes you straight to each puzzle, a page with the rules of the types they contain and, if you want, the solutions at the end. You choose the order, for example from easiest to hardest. On iPad the creation screen puts the puzzle beside the controls when there is room. The glossary covers all four types, and with the Differentiate Without Color setting the board tells the Sudoku variants apart without relying on color. The Support section now has an address to write to us: if you make puzzles for a class, a newsletter or a book, we would like to hear what you need.

GridLab is now on Mac too. The library syncs through iCloud, so a puzzle created on iPad is there on the Mac. ▸ BATCH GENERATION Set the parameters once and choose how many puzzles you want. Each one is saved to the library as soon as it is ready, so stopping halfway never costs you the ones already made. If the constraints are too tight the run stops and tells you how many came out, instead of quietly delivering fewer. ▸ LIBRARY Multiple selection now works for deleting too, not just for exporting. Difficulty and variant filters wrap instead of truncating, and puzzle titles are readable in full. ▸ CREATION Generation no longer holds the screen: you can open the Glossary while it works and find everything on your return. The Duplicate button is now called Reuse Parameters, because that is what it does. ▸ LOOK AND READABILITY New icon and revised accent colour. Badge and label contrast has been corrected where it fell short of accessibility thresholds. On Mac the type has its own scale instead of inheriting the iPad one. ▸ ALSO Fixes to exporting, to the menus and to window behaviour on Mac. The Support screen now says what it is doing during purchase and restore.
