Fibonacci Numbers

Each one is the sum of the two before it.

What is it?

The Fibonacci sequence starts 0, 1, 1, 2, 3, 5, 8, 13 and every later term is the sum of the previous two. It shows up in sunflower spirals, pinecones, and lazy complexity-analysis examples — and only 30 of its terms fit inside the game range.

How it scores

With just 31 hits in a million numbers, landing a Fibonacci number is one of the rarest mathematical traits in RNGdle and scores near the per-trait cap.

The formula: -log2(count / 1,000,001) bits per trait, capped at 20, summed with 0.5 decay per additional trait.

FAQ

What is the biggest Fibonacci number in the game?

832,040. The next one, 1,346,269, falls outside the range.

Is 1 counted once or twice?

Once — the sequence contains 1 twice, but a number only scores the trait a single time. 30 distinct Fibonacci numbers fit in the range.

Why do people care about Fibonacci numbers?

The ratio of consecutive terms approaches the golden ratio φ ≈ 1.618, which links the sequence to spirals throughout nature and design.
