Help & support

Effective 21 October 2026 · Android release 1.0.0

Classic

Tap an arrow whose forward route is clear. It leaves the board and uncovers the painting. A blocked arrow costs one of three hearts. Hold an arrow to preview the path, or enable two-tap moves in Settings.

Genius

Heads are hidden. Edge numbers count how many arrows leave their row or column in the indicated direction. Use the clues to select the correct end. Long-press an end to mark it while thinking. The question-mark button opens the rules introduced so far.

Daily and streaks

Finish five Classic levels to unlock Daily at level 6. A daily puzzle follows your device’s date. Clear any board each day to keep a streak. Seven consecutive days earns three hints and a painting from the separate Streak Collection.

Comfort controls

Pinch to zoom. Toggle grid lines or use a hint below the board. Settings offers Paper, White, Night and Contrast canvases, sound, vibration, animations and two-tap moves. The store listing is available in English/Hindi; the current game UI is English.

Backup and restore

Settings → Backup and restore → Save backup file. Keep it securely. On another phone, choose Restore from file. Review the confirmation: restoring replaces progress on that phone. Cancel leaves current progress intact. Files must be valid Arrow Canvas JSON backups.
