Childhood: The Last Page of the Weekend Supplement

When I was a kid, I'd wait all week for the weekend newspaper supplements. I'd flip straight to the last page, and there, between the crosswords and word searches, I'd find the Battleship puzzle. I'd solve it in pencil — and if I made a mistake, the whole board would become a mess of smudges.

Gradually I developed my own techniques: start with the big ship, think about where it can't fit, close off cells the moment you're sure. I always wanted more puzzles. I was always frustrated it only came once a week. And what I loved most: solving it together with my dad.

Army: Weekends in Front of the Screen

At eighteen I learned to code. During the leave weekends I had from the army, I'd sit in front of my computer — not seeing friends, not going anywhere — just writing code that could generate Battleship boards for me.

The generator worked, but only partially: about 70% of boards were proper puzzles with a single unique solution reachable by pure logic. The other 30% weren't "valid" — they had multiple possible solutions. The secret to generating a provably unique, logic-solvable puzzle stayed elusive.

Today: One Puzzle a Day, for Everyone

Today I'm twenty-nine. With the AI tools that have emerged in recent years, we built together an engine that solves that problem definitively. The engine analyzes every puzzle it generates, verifies it has exactly one solution reachable by pure logic, and rates it by difficulty — from T1 (basic) to T5 (maximum). Every daily puzzle ships at the highest possible difficulty level.

And the best part: the puzzle is shared by everyone. Me, my dad, my mom, my sister — we all solve the same puzzle on the same day and compare times. Exactly the way I always wanted.
