About Card Count
Card Count is a compact PlayMemorize mini-game about working memory and arithmetic. Keep a running tally of positive and negative values flashed at speed.
How a round works. You update a running total as each value appears, then report the final count. Feedback is immediate, and a new seeded round keeps the puzzle fresh without sending the puzzle state away from your browser.
Age-aware practice. Library links can carry an age band into the game, so the opening difficulty is tuned to the child or grown-up challenge path that launched it.
Embeddable. The Embed tab lets teachers, parents, and writers place either the mini-game or full game on another site. Embed opens are tagged for GA4 attribution while play remains local-first.
Part of PlayMemorize, a passion project from Christoffer De Geer. It runs in the browser and is designed for short, honest practice rounds.
