Message text To my experience, sw-based randomizers tend to be unbiased, or very poorly biased.
If they were't, your internet bank account would be open for the taking, since security keys are based on random strings / numbers 
I suspect the fact you are reporting is a mixture of three things:
1. probability: throwing 5 or 6s in a row is not that uncommon
2. cognitive fact: you tend to remember the coincidences
3. statistical law: rare events tend to accumulate
In any case there's statistics tests that can be made on randomizers to check if they're OK. just take note of ALL the dice you throw (say about 500 data points should be enough), place them in an excel spreadsheet, and I'll run a test |
