I built a new gambling game to coincide with my slot machine!
How it Works:In this game the player chooses a number between 0 and 9 (inclusive) and places a bet of $500-$1000 on that number.
I then pull a lever generating a random number which gets sent to a 7 segment display.
(random number generation is the same as my slot machine, except in this case i use 4 bits instead of 5)
if the two numbers match then the player receives 5x their bet as the payout.
getting no lights gives you a respin (a number 10-15, note: these are left over digits from using 4 bit binary, 4 bits generates numbers from 0000 to 1111(bin) or 0 to 15(dec) and you can only display 0-9 on a single 7 segment display, there's a 3 in 8 chance to get a respin)
Betting:bets range from $500-$1000
the payout for guessing the right number is 5x the bet
$2500-$5000 payout
$2000-$4000 profit
there's 10 possible numbers (0-9)
you choose 1 number
hence the chances of winning are 1 in 10
Side Note:unlike my slot machine which is rather small and simple in design this machine uses a 4 bit binary to 7 segment decoder which is quite large and tedious to build therefore i am not willing to build/help build one for you, if you are interested in building one you can use a tutorial such as this one:
