Sumoku is a game of digital numbers. Your goal is simple: create combinations of numbers equaling 10 by sliding them around the grid. Move digits horizontally or vertically “flipping” them into place. Since the numbers are digital, reversing them can change their value. For instance, a 2 can be flipped into a 5 or a 6 into a 9. Be careful to create a non-number in the process since the number cannot be used until it is set right. There are also “special” green and red digits that cannot be flipped but provide you powerful bonuses. You can choose from three modes: Classic - eliminate a set amount of numbers as quickly as possible; Puzzle - get rid of prearranged groups of numbers in as few moves as possible; Endless - do the best score before the grid is full. Sumoku supports iCloud and Game Center (both Leaderboards and Achievements). There are two themes available: Light and Dark.

About

Memo Forms

Features
Read full description

Visual memory game with simple geometric figures and icons. The board consists of several fields (depending on the board chosen) and each one of them hides a form. The idea is to open pairs of fields that are the same. When the two open fields are the same, they stay open and change to green. If they are not the same, the cells change to red and close again. You have to get all the fields of the board left open in the shortest time possible. The app will help you develop your mind by improving and training your visual memory. The game is perfect for everyone, both for the youngest who are developing their memory, and for adults who need to stay mentally fit.
