Hiding GM Dice Rolls?

Are the DM's dice rolls hidden from the players automatically, or is this a feature I can set in the settings?

use /gmroll or /w gm

Or if you prefer inline rolls use /w gm [[d20]]

Here is the wiki documentation for the tip Chell and Mark said, <a href="https://wiki.roll20.net/Dice_Reference#Rolling_in_" rel="nofollow">https://wiki.roll20.net/Dice_Reference#Rolling_in_</a>... Another outside-the-box option is, GM rolls dice at home (real dice). If it's hidden anyway,you can roll at home (added benefit of a realistic dice rolling sound broadcasting on your mic, my players said they like the real sound). Of course this isn't the right solution if you wanted to use Roll20's formulas and pulling modifiers from character sheets in-game for the roll.

A work around: clone your campaign but only for yourself and have it open in a second tab for those gm only rolls. This would give you access to all the in game macros and a roll log for those occassions when players want to know if you actually rolled or not.
