This is a console application for simulating behaviour of a 72x72x72 reel slot machine written fully in Typescript. Program prompts user for number of spins. If you insert '-1' then the simulation for all possible combinations will start. Regardless of simulation mode, the results of simulation will be visible in newly created file after execution 'src/reels.txt' and in console you will get summary of your simulation.
All possible symbols to be drawn on slot machine(3 in one spin):
- SINGLE_BAR,
- DOUBLE_BAR,
- TRIPLE_BAR,
- BLACK_GOLD,
- BLANK.
Install packages using npm install and then just use script npm run start.
You can configure the program changing 'config' object in 'src/index.ts' and changing virtual reel numbers range in 'src/reels.ts'. Default is based on actual machine slot documentation.
Example of result from the program is following:
Enter integer number of spins or -1 for every combination: 100 <-inserted 100 for 100 spins
---------------------------------------
YOU WON TOTAL: 132! <- total win from your game
---------------------------------------
Total spins: 100 <- confirmation of spins executed
coin in: 200 $ <- amount of money inserted to the machine
(you can change current bet at src/index.ts in config, default is 2 dollars)
balance: -68 $ <- amount that you won back in game (totalWin - coinIn)
RTP: 66 % <- percent of the amount that machine slot gave you back in win
you lost: 68 $ <- amount that you lost playing
Example of 2 spins in 'src/reels.txt' file created after execution:
28 2 56 <- numbers randomly drawn on virtual reel
DOUBLE_BAR SINGLE_BAR BLANK <- virtual numbers converted to slot machine reel
you won 0$ <- amount won
36 10 61
BLACK_GOLD SINGLE_BAR BLANK
you won 4$
