About Shieldless
Shieldless: No Shields, ruthless rivals — every +4 lands. 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.
Ruthless rivals read the table: they aim draw cards at whoever is closest to winning, freeze and flip to protect their lead, swap into small hands and fire a Riot Burst the moment it charges.
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? Draw one card and your turn passes.
Special rules at this table
- Stacking: answer a +2 with a +2 or a +4 with a +4 to pass the growing pile to the next player. The first player who can't stack draws it all.
- 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.
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 Shieldless
- Charge the meter with combos. Several plays in a row fill it faster; burst when it shatters your highest-point number cards.
- This mode trains defense on your skill radar and pays ×1.35 XP.
