Memory matching card games

This cluster consists of 21 memory card games that test players' ability to match pairs by remembering positions, with variations in themes, content, and multiplayer options. The cluster's dated history before the index start is sparse and sporadic, with single entries in 2020, 2023, 2025, and 2026, and many members lack source dates. Pablo has the highest traction signal, followed by jogo-memoria and memory-of-home.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
