Pick-a-Number (arcade game)

As this is my third entry to my Creativity Blog, I’m going to share another entry I written on Bell Tree. I came up with a video game that is inspired by Roulette, Medieval Times (restaurant), and ticket arcade games. Last year in 2014, I went to Dave & Busters with my mom while visiting Kansas. This was NOT my first time I went to Dave & Busters, but it was my first time I went in five years. I noticed a few changes. One is that they no longer print out tickets. Every ticket you earn, it connects to your card like Wi-Fi. I thought this was a good idea because there’s less trees to cut down, less risk of someone stealing your tickets, and less to carry as you walk in the arcade.

Now here is the deal. My arcade game idea is where you can pick a number between 1 and 24 and spin the wheel. Like Roulette, numbers have denominations in color and number type (odd and even). Not like Roulette, you can only pick one number at a time, as it goes to different teams and alliances.

In order to play Pick-a-Number, the first thing to do is to swipe the card (or insert tokens based on how advanced the technology is) to give yourself a credit. The more swipes you give it, the higher your winnings will be. However, you can have only up to four credits, and all of your credits get used at once on each spin. Here are the base numbers for what the 1x prize is:

  • One credit – 1 ticket
  • Two credits – 2 tickets
  • Three credits – 5 tickets
  • Four credits – 10 tickets

Once you give yourself credits, your next step is to pick one of the numbers on the touchscreen. There are four rows and six columns. All numbers on the same team are in the same column. You can pick only one number at a time. Picking a second number deselects your first number, so pick wisely before you hit the SPIN button. The wheel doesn’t really spin, but the lights around the wheel move as in a chasing light position. When the light stops, the number it lands on is the winning number. After one spin, the game is over.

The odds of winning have different earnings. When you pick a number, it also picks related numbers, but you won’t get as much tickets as you do if your number wins. Related numbers are numbers of the same color and same number type.

There are three colors in the game, red green, and blue. Here are the numbers to each color:

  • Red – 1, 4, 7, 10, 13, 16, 19, 22
  • Green – 2, 5, 8, 11, 14, 17, 20, 23
  • Blue – 3, 6, 9, 12, 15, 18, 21, 24

All numbers of the same type (odd or even) and same color are on the same team. Selecting one number selects all numbers on the same team, same color, and same number type. Here are the prizes of if the wheel hits your number:

  • Same number – 100x the base number of tickets.
  • Different number, but same team – 50x the base number of tickets.
  • Same color, but different team – 20x the base number of tickets.
  • Different color, but same number type – 10x the base number of tickets.
  • Different color and different type – no tickets.

There are no biased algorithms, so every number has a 1/24 chance of landing, but some may be more often than others, but that’s only because of a randomizer.

Here is an example of what I can win if 20 is my number with three credits:

  • Wheel lands on 20 – 500 tickets.
  • Wheel lands on a green even number other than 20 – 250 tickets.
  • Wheel lands on a green odd number – 100 tickets.
  • Wheel lands on a red even or blue even number – 50 tickets.
  • Wheel lands on a red odd or blue odd number – 0 tickets.

As a result, you have a 1/3 chance of losing, 1/3 chance of only getting 10 times the base ticket prize, and 1/3 chance of getting more tickets. Of the 1/3 chance of getting more, there is a 1/2 chance of getting 20 times the base ticket prize, 3/8 of getting 50 times the base ticket prize, and 1/8 of getting the jackpot.

I could come up with a Pick-a-Number deluxe version or a Pick-a-Number extended version, but right now, I go with the base.
