Help and support
Start with a line
Drag a piece from the tray onto the 8x8 board. Fill a row or column to clear it. Pieces cannot rotate. The interactive How to play screen lets you practise without changing your score.
Why did my board fill up?
A newly dealt Classic tray is checked for a complete placement when it is dealt, but choosing a different order or position can leave no room. This does not guarantee that every choice or an entire game is solvable. Combo Chain shows future trays that may no longer fit when their turn arrives.
Six game modes
Classic is a personal-score game. Daily Deal uses the day’s shared starting deal. Weekly has five score goals. Zero asks you to place all shown pieces and leave an empty board across 301 levels. Combo Chain uses hearts and upcoming trays. Gravity drops remaining blocks after clears.
Hindi and English
The app follows a supported language in your phone preferences, with English as fallback. Open Settings → Language / भाषा to choose English, हिंदी or the phone’s language setting.
Save and move progress
Classic, Daily Deal and weekly stages save locally. Open Settings → Backup and restore to save a file and import it on your other phone. Import replaces the local progress after confirmation; keep a backup first. Zero remembers your completed level, not an unfinished board. Combo and Gravity do not resume unfinished sessions.
Daily puzzles and reminders
Daily and weekly challenges use your phone’s local date. No server download is needed. Reminders are optional and need notification permission; Android power-saving settings may affect delivery.
