Traduzione 
Its very annoying that casinos make progressive jackpots games available without displaying the actual current jackpot value. So, you'll have to click in the game's thumbnail, wait until it loads, and check the jackpot. And if you don't happen to have an account with the casino you would need to register (it seems many casinos do not display the actual jackpot value if you try the Play for Free version)
Also, for those casinos that actually do display the acurrent jackpot amount on the game thumbnails, it would be even better if thumbanails are ordered in descending order according to the jackpot amount.
