Number Blunder has 4 modes, Easy, Medium, Hard, and Very Hard.

A round consists in receiving 5 random numbers between 1 and 1000 and arranging them in a list in ascending order. With an additional 5 numbers added for each harder difficulty.

At the start of the game, you will be presented with the first random number between 1 and 1000. After placing the first number, you'll be presented with other numbers one at a time and you must place them in the list in the correct place so that the list remains sorted in ascending order.

For example, if the first number is 100 and the second number is 92, you'll insert the second number before the first in the list.

Continue entering numbers into the list with each new number that is presented to you, evaluating each number given based on the numbers already present.
