CorgiQuickCalculation app for iPhone and iPad

Corgi Quick Calculate-Brainstorming with three-minute mini games every day will make your quick calculation more powerful.
+ Crazy Arithmetic Every round there will be a very simple arithmetic problem. If you choose the correct answer, you will proceed to the next problem. It will be more difficult to miss the next question, and the time limit will be stricter.
+ Crazy Guess This is another very simple mini game. Corki will give you a question to let you judge which one of "stone, scissors, cloth" wins. As the number of questions increases, time will decrease.
