Today we’re thrilled to announce the next game in our PvP skill gaming portfolio.
Introducing: 21 or Bust. THNDR’s competitive twist on Blackjack is available now.

But this isn’t just a Blackjack remake. 21 or Bust is a skilled PvP format where two players go head-to-head using the same exact deck. There’s no dealer, no house, and no luck involved. Just pure competition.

The goal? Hit 21 as many times as possible without busting. Build combos, use wild cards wisely, and outscore your opponent.

How It Works

In each 3 minute match, you and your opponent receive the exact same 52-card deck, with two random cards replaced with wild cards. You’ll take turns placing cards into four columns, trying to stack each one to reach exactly 21. Here are the basics:

• Hit 21? The column clears, and you score a jackpot (each card in a column = 100 points).
• Go over 21? That’s a bust and you lose 500 points.
• Use a wild card? It fills the column perfectly to hit 21 and clear it.
• You get +10 points for every card you place, and your score can’t go below 0.
• Finish early? You can press ‘End Game’ at any time to lock in your score.

Why It’s Different

This isn’t the Blackjack you’re used to.

• No house. You play head-to-head against a real competitor.
• No luck, just skill. Strategy, memory, and precision matter more than luck.
• Wild Cards. New twist = new strategy. Use them wisely.

Think ahead, manage risk, and know when to take a chance or when to walk away. Every card counts and every point matters.
