Rising Keep: questions

Before you play

I've never played a falling-block game. How does it work?

Pieces of stone, timber, plaster and tile drop from the quarry. Drag to slide one, tap a side to turn it, swipe down to set it. Fill a course from wall to wall and it seals into your castle.

Can I lose my castle?

Never. Once a course is sealed it's part of your castle for good, and if you fall short of a commission, the courses you sealed still pay.

Which castles can I build?

Twelve, in three books: Kumamoto, Matsumoto, Himeji and Nagoya; then Carcassonne, the Alhambra, Mehrangarh and Jiayuguan; then Inuyama, Hikone, Matsue and Osaka as it stood in 1615. Legends like Azuchi and the Dragon Palace rise as you crown storeys.

Is the history real?

Yes, or an honest old legend. Each painting tells its story in four bands. One of our favourites: in 1872 Matsumoto's keep was sold off for its timber, and the townspeople bought it back.

It's getting too fast. Can I slow it down?

Yes. Turn on Steady Hands and the pieces fall at a calmer pace. Only the master's test insists on full speed.

What do I have to pay for?

Nothing to start. Book III, the Master Mason's Path and the Patron of the Keep are optional purchases, and Book III's first site opens free once you've raised Kumamoto. Every look in the game can be earned with koban.
