One card. One decision.
Tap when the current and previous cards add to 13. Always tap a King.
A = 1 · J = 11 · Q = 12 · K = 13. Number cards use their printed value.
For the very first card, tap only a King. Every card becomes the previous card, including Kings and cards you tapped.
A wrong tap ends your run immediately. Missing a required tap ends it when the card changes. Each completed card window earns one card survived.

Live 1v1
Both players see the same stream on the same schedule. If a player fails card N, the other must correctly complete N+1 to win. If the other fails N or N+1, it is a draw.
Ranked changes Glicko rating. Casual and friend rooms do not. There is no total daily Ranked limit. The same pair may play up to three rated matches per rolling 24 hours with a two-minute repeat cooldown.
Controls and timing
Use a fresh touch, pen or primary mouse press, or press Space. Holding does not repeat. Extra presses on one card are ignored. Keep the page visible: there is no pause or competitive resume.
Speed gradually rises on an absolute 120 Hz logical schedule, independent of display refresh rate. A 60 Hz display can play the same game. Network and frame interruptions can stop verified play.
The deck
Each bag contains all 52 physical cards once. It is exhausted before replenishing. BAG-R1 gives 14–18 tap targets per bag, no more than six quiet cards or three consecutive targets, including bag boundaries. Repeated Kings have different suits.
