About this app

"Block Count 200q" application is an application that counts and responds to the number of building blocks. As we imagine and count building blocks hidden in a stack, we can cultivate space recognition power. There are 200 questions in all. Level 1 has 15 questions in only the first row. Level 2 is a stacking problem up to the 2nd step, there are 45 questions. Level 3 is a stacking problem up to the 3rd stage, and the number of building blocks increases as you go to levels 3 - 1, 3 - 2, 3 - 3, and 3 - 4. Level 4 is a stacking problem up to the 4th row, there are 10 questions. When you get used to the problem, please turn on the random switch at the bottom right of the screen. The order in question is random. Select the level on the menu screen and start counting. The number of building blocks is counted with "+" and "-" buttons and answered with the "Answer" button. Go to the next question with "Next" button and move to the previous question with the "Prev" button. You can challenge the current question with the button of ""Redo"" again. The number of correct answers and incorrect answers are totaled at the end and the results are displayed. If you answer the same question more than once, the result of the last answer will be recorded. You can return to the menu screen at any time with "Menu" button.
