UK betting bonus

[Cubswin]

few questions regarding their bonus for certain hands....

1) Are their servers on EST or GMT? I assume its the latter?

2) Todays bonus is 40-60 pounds for being dealt QT7 all hearts... that means you just make this hand by the river?

3) Do you have to show down your hand?

their website doesnt really specify anything so maybe someone has some experience claiming one of these.

thanks
