One quick 2-player duel. About 90 seconds.
What is Prism Riot?
Prism Riot is an original shedding card game from Dixon App Studio. Everyone starts with seven cards. On your turn you play a card that matches the active energy — Flare ▲, Surge ●, Volt ◆ or Void ■ — or the symbol on the top card. Action cards bend the rules: FLIP reverses play, FREEZE skips a rival, +2 and +4 make them draw, SHIELD blocks the next attack aimed at you and SWAP trades hands. Wild PRISM cards play on anything. First to shed every card wins and scores the points left in everyone else's hand.
Two ideas make it a riot. The Riot Meter charges with every card you play and faster with combos; at 100% you can burst and shatter two number cards at once. And the rule packs change everything: Merciless brings +6, +10, PURGE and a 25-card knockout rule, Eclipse flips the table to a dark side where actions get harsher, and Eruption turns the draw pile into a volcano.
The web version includes all 58 modes from the Prism Riot app and adds 7 new ones you can only play here: Jump-In, Last Card Call, Doubles, House Party, Jump-In Duel, the Endless Gauntlet and the Daily Duel. There are 50 table modes against the computer, 120 puzzle levels, ten bosses, a six-tier cup, a Daily Rift, weekly challenges, 60 player levels, streaks, quests, achievements and unlockable table themes and card backs.

Is Prism Riot like UNO?
It's in the same family of colour-matching shedding games — match the colour or the symbol, play action cards, be first to empty your hand — but Prism Riot is an original game with its own cards (FREEZE, SHIELD, SWAP, PURGE, ECLIPSE, BLAST…), the Riot Meter and 65 modes. It is not affiliated with Mattel.
