Update: As it turns out, there's many more where that came from. Carcassonne is part of Amazon's current "Over $100 in Essential Apps FREE Thursday and Friday Only" deal. It's joined by a slew of free apps and games.
There's always a free app of the day in the Amazon Appstore, but sometimes consumers are treated to multiple giveaways on the site at the same time. Today's free app, Sorcery, is joined by Carcassonne, which just happens to be going for the glorious price of $0.00 at the same time. Both of these games usually run $4.99, making this a great chance to save yourself ten bucks and have a little fun in the process.
Sorcery combines Choose Your Own Adventure with tabletop RPG gaming to provide an immersive and largely text-based experience. It's not for everyone, but if you're up for something different, don't mind reading, and are in the mood for some rather amusing artwork, this one may just be worth a look.
Carcassonne is a tile-based board game, so you may want to reserve this one for a tablet. The developers have done an admirable job porting the experience to Android, allowing up to four players to compete in a local multiplayer match. You're also free to go it alone against AI opponents instead.
Sorcery will stop being free at the end of the day. Since we're not sure why Carcassonne's also discounted, we can't say for sure when it will return to full price. Sometimes there are simply just two free apps of the day. If you're interested, might as well hop on them both while you can.
