What’s new

Fixed ads loading endlessly with no impressions, and hints/rescue now use a single interstitial instead of stacked rewarded ads. Daily Puzzle now resumes right where you left off if you exit mid-puzzle. Added a 7-day Streak Restore options and a one-time Remove Ads purchase . Also fixed a bug where switching Google accounts on the same device could mix up progress between accounts.
