Sevens is a unique number-based puzzle game that requires placing tiles from one's hand into a playing board. The objective is to position all tiles in the board so all numeric sides that touch equal seven. Sevens builds on the concepts of other number games, like Sudoku, that require the player to use arithmetic and strategize where to properly play numbers (tiles).
Sevens is easy to pick up and play, consisting of simple and intuitive mechanics that make it inviting to new players, but also manages to retain its challenging gameplay as players progress to later levels.
This version includes 12 playable levels in the Emerald tier. There is an in-app upgrade option to unlock the remaining 36 levels contained in the Amethyst, Sapphire, and Ruby tiers.
INTERNET, BILLING, ACCESS_NETWORK_STATE - Requirements from Google Play Services that allow in-app upgrading.
