rainbow-trail

Rainbow Trail is an original color-card path race for two local players. Coral and Teal draw color cards, move to the next matching tile, and race to tile 36 on a bright Three.js trail board.

The app keeps the board front and center with animated pawns, candy-bright color tiles, subtle trail ribbons, top race stats, and bottom controls for the frequent draw action plus a finish drill and new round.

What you can do

• Draw from the bottom bar: The card action advances the current pawn immediately.
• Read the color trail: Pawns jump to the next tile matching the drawn color.
• Race to the finish: A player wins by reaching tile 36.
• Practice the finish: The drill loads a terminal rainbow-card position.
• Share one instance: Synced-store keeps the race state consistent across clients.
