RNGdle
RNGdle is pure luck: one roll of a random number each day. You cannot plan it, but special numbers earn badges, and everyone compares their rolls.
Pure luck, once a day
RNGdle gives you one roll of a random number each day. There is no skill involved and no best strategy. The fun is in the badges: some numbers have interesting properties, and rolling one earns you a badge to show off.
What makes a number interesting
The badge list on the site shows every property you can collect. The kinds of things that make numbers special in general include:
- Prime numbers, which divide only by 1 and themselves.
- Palindromes, which read the same both ways, like 12321.
- Repeated digits, like 7777.
- Powers of two and perfect squares.
The sandbox
The sandbox lets you roll freely to see how the badges work, without touching your daily roll. It is a good way to learn what the best number would look like, even if you can never choose it.
