Start with 10 free cases. Decode cryptograms, connect the evidence, and decide what really happened. Can you crack the case? 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 adds 11 new mysteries with 33 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. 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.
