Are Online Dice Rollers as Fair as Real Dice?

Last weekend, we were playing a board game when someone realized we’d lost one of the dice, so we decided to use an online dice roller instead. It worked perfectly fine, but one of my friends started questioning whether digital dice are actually random or if the results follow some hidden pattern. I’ve always assumed that online randomizers are reliable enough for casual games, but now I’m curious about how they really work. Do you trust virtual dice rollers, or would you rather stick with physical dice?
