So I'm making a simple kids game, its letter and column game in which if the user slides the correct letter in the selection area and hits the lever a the end, it either confirms the answer or says incorrect if the user got one of those questions incorrect. Such as if the user is suppose to spell the word "cat" by tapping on each block as it slides up and down, when he/she hears the correct sound, they leave it in the selection box and moves onto the next column until all letter have been paced. Then if all the right block have been placed correctly, and the confirmation button(lever) is pressed, it actually goes to the incorrect or correct feedback.
Link to my mockup to give a better example:
How can I achieve this? Any help would be appreciated!
