About Reaction Royale

Reaction Royale is a real-time 2-player reflex duel on Couplescade. Best of 5 rounds, mixed cue types — simple reflex, go/no-go impulse control, and odd-one-out — fastest finger wins each round.

No app download needed. One player creates a room, shares the 4-letter code, and the other joins instantly from any device. Works across phones, tablets, and desktops with full cross-play support.

Each round is measured locally and fairly so network speed never decides the winner — only reaction time does. Available on Web and Google Play.
