In my campaign, we have to play over google meet, which is fine and all, but I'm starting to get ever so slightly suspicious of my players. they can't seem to roll below a 15 on anything but initiative, and I can't see their rolls because of how we have to play. It's so weird, they succeed way more than statistically likely. any tips on how to deal with this problem, or a least get my eyes on their rolls?

I can't tell you whether the players are cheating, but if you want visibility, the only real option is to use an electronic die roller that automatically shares its results. It looks like someone has written one for Google Meet, but I cannot tell you how good it is as I don't use Meet.

My group uses roll20 where all the rolls except the DM's are public (and he certainly rolls low every so often). And I have a webcam setup pointing at a dice tray so as long as he can see the number clearly, it's a valid roll.

I am not familiar with Google Meet but not being able to see dice rolls is a little bit insane to me. At any in-person table you can usually just adjust in your seat and see what the other players are rolling to discourage this very thing.

yeah, I do have one player who rolls as expected, my little brother who plays with us. the others haven't failed a roll/check since an 18 to hit against an AC 20 mini boss. that was roughly three sessions ago. i'll try roll 20 and see if they just are absurdly lucky, thanks for the advice.

If you ain’t cheating, you’re not trying. Law of averages will automatically tell you that you will miss at least 1x. You would need to have a digital di rolling option if you are going to play virtually. Even at a table top I would question the rolls if they never miss.

I've just been wondering if they have really good modifiers, but druids and fighters don't get expertise i don't think, and at level seven their proficiency bonus should only be like +3 or something. 

I hate to accuse anyone of cheating but at level 7 there's no way a Fighter and a Druid should be succeeding every time, that's just statistically unlikely. Is it just combat or do they pass skill checks easily too? Because a Fighter especially would normally be dumping the mental abilities making their odds on skill checks like Investigate or Perception even lower

they are combat monsters but I do give regular perception checks every time they enter a new area, just to see how much they clock, and they've been rolling a lot of deception recently too, they're doing an infiltration. i will say real quick, the fighter has a relatively unique spread, dex based with some focus on int and dumped str. maybe i could give them a bunch of strength checks and see how it goes. we meet next tomorrow though, and if anyone knows a way I can get my eyes on their rolls i'd appreciate it. they both use DnD beyond too, so is there a tool on here I can use?

If they're rolling on D&D Beyond and you're all in a shared campaign then there's a roll tracker for you to check the history. If you're the DM in a shared campaign you can also access everyone's character sheets which will help figure out what sort of stats they've got. I run a kids club and regularly do both of these not because I think they're cheating but to make sure they're not forgetting anything

As people are more tech savvy then me, ask for a screen shot of the dice?  But not all the time and after they tell you the score.

You can also ask them to roll and send you the PM using the dice ability in here and PMs.
