What's New in Sudoku Collector
1.2.4
July 24, 2026
What's New in 1.2.4 • Daily puzzles now stay up to date — the latest month always appears, and you can scroll back through a full year of past dailies. • More accurate technique credit: the victory screen now reliably recognizes every solving technique you used, including trickier cases the previous version could miss. • Your progress is safe if you leave mid-puzzle — techniques you've already used are remembered even after fully closing the app. • Cell coloring stays out of your way — the digit you're tracking stays highlighted while you color, and coloring no longer places a number by accident. • Various stability and correctness fixes to the solving and hint engine.
