What is regexle.com?

Regexle is a daily hexagonal crossword puzzle with a twist: instead of filling in words, you fill in alphanumeric sequences that must satisfy regular expressions listed along the edges. Each rule acts as a clue, and your job is to find a set of characters that makes every edge match its pattern.

How to play regexle.com

The puzzle presents a hexagon grid with a regex rule on each side. You fill cells with characters (letters, numbers, or symbols) so that each row, column, or diagonal—depending on the axis—forms a string that fully matches its corresponding rule. Empty cells are treated as spaces, and a rule turns green when satisfied, red when not. You can navigate with Tab and Shift-Tab, or click a rule to focus traversal along that axis. A hint mode highlights correct and incorrect cells, and the game tracks how many hints you use.

Tips & strategy

• Rules must match the entire string, not just a substring.
• Use the built-in traversal shortcuts to move efficiently.
• If you're new to regex, external resources like regex101.com can help you understand pattern syntax.
