We just released 42,207 more quality cryptogram puzzles for Android & Kindle. This all you can eat monthly subscription also includes the other 9 add-on volumes (Politcal, Funny, Killer, etc). Download for your device from here. iOS is "coming soon".
Just like the quote volumes, these 40,000+ quotes include expert times, difficulty rating, background author bios and are carefully checked to be free of typos or other errors.
You can cancel anytime and play until your month ends. Your played games are remembered, so it is completely ok to stop and start as time and interest allows.
