Online Casino

  i don't know if this is common knowledge but vegas slot casino and joker vegas casino are the same casino. i was playing at joker vegas and then went to vegas slot casino and noticed some of the jackpot thermometers were similiar. so i downloaded both of the casinos and compared the jackpot thermometers and omg they are exactly the same. is this legal to have one casino with 2 names? also, i played at vegas joker for about 2 months and there are 4 games that are at 999.00 for the whole time....they don't pay out anything and jackpot has never paid out for at least the 2 months i have been playing there. (same games as vegas slot). 
anyways, i thought i would mention it in case nobody else noticed this.
