Every detail designed to keep you focused on the puzzle.
4 Difficulty Levels
Easy, Medium, Hard, and Expert — each with its own score multiplier, clue allowance, and
number of cells removed. The same board generation algorithm ensures every puzzle has a
unique solution.
Score & Streak System
Earn points for every correct placement, with bonuses for completing full rows, columns,
and 3×3 grids. Win streaks are tracked per level — keep your errors under 3 to protect
them.
Timer & Clue System
The timer runs throughout the game and increases the score penalty every 30 seconds.
Stuck? Spend points to reveal a cell — but clues are limited per difficulty, so use them
wisely.
Per-Level Statistics
Best time, max score, total games played, and win streak — tracked separately for each
difficulty. All data persists locally via SQLite and survives app restarts.
Haptics & Sound
Two haptic intensities for cell taps and a distinct triple-pulse pattern on game
complete. Optional sound effects for every interaction. Both can be toggled and persist
across sessions.
Dark & Light Mode
System-aware theme with manual override. The color mode persists to the local database
so your preference is always remembered — no cloud account required.
