What?
My reaction exactly.

Pretty sure this just refers to the maximum win on a single dice bet, not any jackpot or anything.
That's what it says.
Maximum winning amount on single bet at dice is now 5 BTC!
Due to a rising bankroll size (and hence investors security), the maximum possible amount to be won in a single dice bet has been increased to 5
BTC.
What you need to do for that? Place a bet at the according size/payout and win.
What was required to deposit in advance
Doubt you're gonna reach 5
BTC from faucet, but hey, feel free to try.
And if there is a particular bonus to get the prize / bonus 5 BTC
Nobody said anything about a bonus.
what only one round on all bets in this Dice game, or many times will get a prize of this ..
After 220 winning bets at that size our bankroll is emptied up, so I guess that would be the limit
