About Blitz Duel
Blitz Duel: 2 players, 5-second turns. Chaos tables change one big rule — stacking, timers, bigger hands, extra wilds — and see what happens.
The table
2 players: you and 1 computer rival. 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? Draw one card and your turn passes.
You have 5 seconds per turn. When the bar runs out you draw automatically — a small tick warns you in the last three seconds.
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.
- 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.
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 Blitz Duel
- Decide before your turn starts. Plan your next card while rivals play, and never let the timer draw for you.
- 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 speed on your skill radar and pays ×1.35 XP.
