Keno Game Simulator
This is the empty board at the start of the game
The player here selects 17, 21, 39, 44, 56, 57, and 64
The computer chooses 20 random values from the board and the player matches values 44 and 56. Based on the payouts from the lottery, this player would be rewarded nothing
Language(s) Used: Java + Apache NetBeans IDE
This project is just a replica/simulation of the classic lottery game, but without the gambling. The game requires the player to choose up to 12 values from a board of 80 numbers. Once the player is done selecting their values, 20 randomly selected values are chosen from the board by the computer. The player will then be rewarded based on the number of matching values they share with the computer.
Shown below are screenshots of how a typical game may play out.
