Knotilus

Knotilus is a daily number puzzle where you must uncover three Fibonacci-style sequences hidden among ten numbers.

Each valid sequence:

• Has four numbers in increasing order.
• Follows the pattern where each number (starting from the third) equals the sum of the previous two.
• Shares one special number "the knot" that appears in all three sequences.

Your goal: find the three correct sequences that use every number exactly once.

How to play:

• Tap four numbers to propose a sequence (see example below).
• Valid ones lock in automatically.
• When you’ve found three sequences, you can click on the "knot" number that connects them. This is simply the common number between all sequences.
• You may also continue to find all sequences before identifying the knot.
• Optional: toggle Easy (visual cues) or Hard (no hints) before starting.

Example answer:

A valid sequence would be: 2, 15, 17, 32

This works because:

• 2 + 15 = 17
• 15 + 17 = 32

Why we like it:

• ✅Elegant blend of logic, math, and pattern recognition.
• ✅The "knot" mechanic adds depth.
• ✅Feels fresh every day, part Fibonacci, part logic, all brain-tingling fun.

Hint: If you're stuck, pick a larger number and then scan for two smaller ones that add up to it.
