Remember Me?

There are three difficulty levels to choose from: Easy, Medium, and Hard. In each difficulty level, you will be shown a series of distinct emoticons (varying number of emoticons for each difficulty level) during a time period of 30 seconds. Your task is to remember these emoticons. At the end of 30 seconds, you will be presented with a random mix of emoticons (the count of emoticons shown here will be higher than the count of emoticons you have to remember) from which you have to select the ones that were shown to you.
As described above, there are three difficulty levels to choose from:
- Easy: In easy difficulty level, you are given a total of 10 emoticons to remember in a time duration of 30 seconds. Then, you have to select the 10 correct emoticons from a pool of 30 emoticons (10 correct + 20 wrong emoticons).
- Medium: In medium difficulty level, you are given a total of 15 emoticons to remember in a time duration of 30 seconds. Then, you have to select the 15 correct emoticons from a pool of 40 emoticons (15 correct + 25 wrong emoticons).
- Hard: In hard difficulty level, you are given a total of 20 emoticons to remember in a time duration of 30 seconds. Then, you have to select the 20 correct emoticons from a pool of 50 emoticons (20 correct + 30 wrong emoticons).
You get one point for each correct emoticon you identify or recall. However, for each incorrect emoticon you select, you lose a point. The lowest score is capped at 0, so you cannot score in the negatives. There are no penalties for failing to recall emoticons. This is designed in such a way to discourage the users from selecting all the emoticons and scoring 100% every-time.
