Daily Hidden Cat

What

A casual puzzle mini-app where players find one hidden cat in five AI-generated 9:16 isometric watercolor illustrations daily, finishing each in 30 seconds to 2 minutes. A difficulty curve from easy to hard maintains completion motivation, with paw stamps earned per discovery. Illustrations are generated by Vertex AI Gemini 3.1 flash-image-preview, validated through Flash/Pro stages, and stored in R2, refreshing the puzzle pool with new illustrations every day. Light monetization combines a bonus lottery mechanic and opt-in rewarded ads in the result sheet. Available as a Toss mini-app.
