Round 2 - Machine Coding Round
Questions:
- Implement a memory game, that has a fixed number of blocks. Ex: 5 (programmatically configurable).
- Start the game on click of START button.
- Start blinking the blocks one after the other, starting from the count of 1. (single blink).
- The blinking of blocks must be completely random and the same block may blink twice in sequence.
- Let the user click the blocks in the same order of appearance.
- If user clicks are accurate, continue to the next level with the increased count.
- Else shake the container to indicate the wrong click and start over.
- Maintain the current score and highscore of the game.
- Store the High Score in Local Storage to persist over refresh.
