- 📦ice sudoku updated to version 6.1.0• New “Bidirectional Cycle” hint technique: hints and difficulty analysis now recognize and explain advanced cycle structures, covering more top-tier boards.
• Overhauled puzzle generation: clues are dug cell by cell with uniqueness verified at every step, making puzzles more stable and high-difficulty tiers more reliable. Every puzzle can be reproduced exactly from its recorded seed.
• Major performance gains: uniqueness checks now use an exact counting engine, roughly 9× faster per check; combined with multi-core racing (about 2.4× speedup), everyday puzzles generate noticeably faster, and the worst-case time for top difficulty is roughly half of what it used to be.
• Custom sudoku made easier: the editor opens with a centre-symmetric recommended pattern that can be reshuffled in one tap, generation retries intelligently, and unreasonable patterns are explained before or instead of a failed run.… more - 📈ice sudoku entered the top 10 on iPad · Top Paid All AppsPH

Review momentum

faster than 52% of Utilities apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
