Atomas is a fascinating puzzle game, which you can learn in seconds but will entertain you for weeks. The perfect game for your spare time! Your little universe starts with hydrogen atoms only but with the help of the energy rich plus atoms you are able to fusion two hydrogen atoms into one helium atom, 2 helium atoms into one lithium atom and so on. Your primary goal is to create the valuable elements like Gold, Platinum and Silver. But watch out, if your universe is overfilled with too many atoms it will cause a big crunch and the game is over. One way to prevent this is to build up long symmetries in your atoms and start big chain reactions. From time to time minus atoms appear, use them for absorbing and replacing atoms within your universe or sacrifice them for a plus atom. You see Atomas is not hard to play, but if you want to get to the top you'll need a good strategy, which keeps your atoms organized. By creating new elements like oxygen or copper you unlock lucky charms, which effect the game in various ways and adjust it to your strategy. What Atomas offers you: - 4 different game modes - simple but addicting game mechanics - 124 different atoms to create - 12 different lucky charms - exciting challenges - compare your scores with friends via GameCenter - share your score on twitter and Facebook - quick tutorial The developers high score is 66 534.

"Bulls and Cows" is a game where the goal is to guess a secret number generated by the program. All digits in this number must be different. There are various versions of the game, which can be more or less complex. This allows the game to be played by experienced or beginner players, as well as players of different age groups. After entering your guess, you receive a hint in the form of the number of bulls and cows. A bull is a digit that is in the correct position in the secret number, and a cow is a digit that is in the secret number but is in the wrong position. For example, if the secret number is 5234 and you guessed 4631, then you would get the hint 1 bull (for the digit 3) and 1 cow (for the digit 4). The following game modes are offered: 1. Classic game - on each turn, you try to guess the secret number; 2. Puzzles - you are given a set of moves based on which you must immediately guess the secret number; 3. Play against the computer - you and the computer take turns trying to guess the secret number; For each game mode, there are two difficulty levels: "Easy" and "Standard". In easy mode, it is known exactly which digit of your guess is a bull, a cow, or is not in the secret number. In standard mode, it is only known how many bulls and cows your guess contains, but it is not known which specific digits are bulls and cows. The game continues until you or the computer (game mode 3) guesses the secret number. Each win will bring you great pleasure. Good luck!
