Christmas App Giveaway!
Help yourself to a promo code for Tapt, Déjà or WordFlash! Each code is for the in-app purchase to unlock the full game, and remove ads. Just make sure to install the game, then tap to get your code, and tap again to go to the App Store and redeem it (or you can copy/paste it manually).
If it doesn't automatically show up in the app, try restoring purchases and it should work.
