About Mayhem
Mayhem: Stack +4 on +2, 7 swaps, 0 rotates, draw till you play. Chaos tables change one big rule — stacking, timers, bigger hands, extra wilds — and see what happens.
The table
4 players: you and 3 computer rivals. Everyone starts with 7 cards.
Sharp rivals shed high-value cards first, save their wilds for the end and keep the colour they hold most of alive. They are the standard opponent.
The deck
The table uses the 126-card Prism deck: numbers 0–9 in four energies (Flare ▲, Surge ●, Volt ◆, Void ■), two each of FLIP, FREEZE, +2, SHIELD and SWAP per energy, 6 PRISM wilds and 4 +4 wilds.
How a turn works
On your turn, play one card that matches the active energy (colour) or the symbol of the top card. Wild cards play on anything and you choose the next energy.
Can't play? You keep drawing until a playable card turns up (up to eight), and your turn continues so you can play it.
Special rules at this table
- Stacking with cross-stacking: answer any +2 or +4 with another draw card — including a +4 on a +2 — and the whole pile moves on to the next player.
- SHIELD cards stay in front of you and block the next draw attack aimed at you, however big it is.
- The Riot Meter charges with every card you play; combos charge it faster. At 100% hit RIOT BURST to shatter up to 2 number cards of the active energy at once.
- Play a 7 and you swap your whole hand with any rival you choose.
- Play a 0 and every hand rotates one seat along the direction of play.
How to win
Be the first to shed every card. Your score is 100 for the win plus the points left in your rivals' hands, a speed bonus for quick wins, 25 per Riot Burst, a combo bonus and 50 extra for winning without drawing a single card.
Tips for Mayhem
- A 7 is a comeback card: hold it until your hand is bigger than a rival's, then swap with whoever has the fewest cards.
- Charge the meter with combos. Several plays in a row fill it faster; burst when it shatters your highest-point number cards.
- Play a SHIELD early when your hand is large — it waits in front of you and eats the next +4 or +10.
- This mode trains aggression on your skill radar and pays ×1.3 XP.
