Decode & Deduce: Cryptogram

Decode & Deduce is a cryptogram mystery game. Decode substitution-letter messages, read the evidence, and choose the conclusion that fits each case. Start with the original 10 cases, which remain free. Case Pack 1 contains 21 mysteries with 63 cryptogram puzzles. Unlock the pack with one purchase, including all hints, replays, and updates to these cases. There is no subscription. Future case packs are separate. Already own Case Pack 1? The 10 added cases are included with your existing purchase. The app uses English. To restore an owned pack, open Settings and tap Restore Purchases. Restoring purchases unlocks owned cases; it does not recover local puzzle progress.
