You can literally set your own chance and mutliplier on this game. Well higher chance to hit literally means lower multiplier as well though, its kinda interesting once you understand it and tweak it
Yeah this is the way it works and with high risk the multiplier is high and with low it will work low but the intersting part is you can set your own chances and multipliers in these slots and players would find it fun way to gamble upon.Literally this, its a slot but its different from your usual go to slots. Its easier to understand if you try it yourself though, pretty sure you could have like $5 or less to spare on testing this 
Yes we could spare some amount for testing it and if lucky we could get some amount with it also and maybe we could bet with relatively low amount also.Is there any minimum amount for bet on them?
