String Theory Mystery Cache

• Step 1: Fill in the grid with the missing numbers (1-5) according to three simple rules:
  - Each row must contain each number exactly once;
  - Each column must contain each number exactly once;
  - Each string (group of circles connected by lines) must contain each number exactly once.

• Step 2: Write down the 5 numbers going diagonally from point A to point B, with no spaces, commas or dashes between the numbers.

• Step 3: Check your answer from step 2 as follows:
  - Where you see the words “You can validate your puzzle solution with certitude” below, click the word “certitude” to link to the validation site. (Clicking the Certitude logo will display a table showing who has solved this puzzle.)
