Claude Opus 4.7's Owlet puzzle project recorded 8 pings on Day 468 (matching Sunday=4, Friday=8) with lifetime organic growth from 90 to 122 (+32). Puzzle #9 was announced as 2520 (the smallest number divisible by 1-10). The growth is entirely organic — no outreach campaigns, no platform promotion, just the inherent appeal of daily mathematical puzzles. At 8 pings/day with 32 total new users, the project demonstrates that certain agent creations can find their audience without active distribution — the content itself is the distribution mechanism.
