This is a simple and beautiful matching game that will challenge both your pattern recognition skills and your strategic planning skills! * More than 300 levels! * Available on both iPhone, iPad and AppleTV! GAME RULES Match the patterns in each level and complete as many necklaces as possible. To pass a level, you need to fulfil the level's goal before you're out of moves. GOALS The levels can have three different types of goals: * SCORE A score goal requires that you gather a given number of points before the game ends. You earn points for each pattern you complete. The number of points increases with the number of completed patterns in the necklace. The first completed pattern in a necklace will result in 1 point, the second in 2 points, the third in 3 points, etc. You will also get extra points for each completed necklace - the points will match the number of completed patterns in the necklace. * PATTERNS A pattern goal requires that you complete a given number of patterns before the game ends. The number of gems included in a pattern vary from level to level.ย When you add a gem that breaks the pattern in a necklace, the necklace will be destroyed and a new pattern will be created for you. * NECKLACES A necklace goal requires that you complete a given number of necklaces before the game ends. A necklace is complete when all gem holders in it are filled with gems that follow the initial pattern. When a necklace is completed a new pattern is created and you can continue to build the new necklace. CHEATS There a different types of cheats that can help you save game moves and keep the necklaces intact: * THROW AWAY GEM This gives you the ability to throw away the current gem and get to the next one without losing moves or breaking a necklace. * REPLACE GEM This gives you the ability to replace the current gem with a gem of the type that you need the most. * LOOK AHEAD This gives you the ability to see what gems are coming after the current one. It with help you plan your moves better and make it possible to distribute the gems to the available necklaces in a smarter way.

One: the game that lights up your mind The goal is to set all cells on the board to 1 with a sequence of clicks. When you click on a 0, the cell is set to 1; when you click on a 1 the cell is set to 0. In addition, each click changes the current state of the entire row and column that contain the cell you've clicked.

Verdict
The clearest difference is in-app purchases: Oneing at none against Gemica's 7. Gemica's advantage is ads (none vs shown) and device support (4 vs 2). On price, update cadence and iOS requirement there is nothing between them.
