Flip card game rules: light side and dark side
Updated September 25, 2026
Flip-style card games give every card two faces. At some point a special card flips the whole table — the discard pile, the draw pile and every hand — to the other side, where the cards are nastier.
Prism Riot's Eclipse pack is an original twist on the idea. Instead of printing two decks, each action card has a dark twin: when someone plays ECLIPSE, the whole table goes dark and every action plays as its twin until the next ECLIPSE.
The dark twins
- FREEZE → FREEZE ALL: everyone else loses a turn and you play again.
- +2 → +5: the next player draws five.
- +4 → ROULETTE: pick an energy; the next player draws until they find it.
- SWAP → PURGE: discard every card of that energy from your hand.
- Numbers, FLIP, SHIELD and PRISM stay the same.
How the flip works
Play an ECLIPSE (it matches like any energy card) and the table flips — the Prism Riot table glows violet and your cards show their dark faces with a 🌑 badge. Legality uses the effective face, so on the dark side a +5 matches a +5, not a +2. Play another ECLIPSE to flip back.
Strategy
- Before flipping, look at your actions: if they get stronger on the dark side, flip; if a rival's likely +2s become +5s aimed at you, don't.
- Flip with a small hand — the dark side's FREEZE ALL and PURGE finish rounds fast.
- Umbra, the Eclipse boss, plays best in the dark. Flip back to fight her.
