Prism Relay

One complete classic108 hand with seven cards each, matching numbers/colors/actions, Skip, Reverse, DrawTwo, Wild and challengeable WildDrawFour. No stacking. Call ONE and catch missed declarations; a drawn card alone may be played or passed. Recycle the discard pile, resolve final draw penalties and score remaining cards.

Solo: one human against one to five labeled information-limited bots. Online: exactly two to six signed-in humans, no local seats. The trusted server shuffles and keeps the deck/hands, sends each seat only its permitted information, validates legal actions and owns the result. Host cannot inspect other hands or forge the result.

Landscape preferred; portrait and native Standard/Theater/Fullscreen preserve the table. Solo untimed, online60s; timeouts draw/pass/accept+4/choose initial Coral. Help stays live. Departure closes without a result; no reconnect/migration. One hand instead of the optional500-point match; a declared2048-turn digital safety draw.
