Master the rules, control the saw, and outplay your opponent in Roblox’s Twenty One. Ready to survive your first match?

Twenty One straps you to a table, slides a buzzsaw overhead, and turns Blackjack into a fight for digital survival. Each round starts with a quick bet that decides how far the blade creeps toward the loser, then deals two cards worth one to eleven points apiece.
Your job is simple: draw, stand, or drop a Trump card to land as close to 21 as possible while keeping the saw on the other side of the room.
Everything About Twenty One Roblox
Twenty One is a Roblox game inspired by Blackjack, but with a horror twist. Your goal is to score as close to 21 as possible using a mix of strategy, timing, and card knowledge. The stakes are high as each round moves a buzzsaw toward the losing player. If it touches you, the game ends in your virtual death.

The game starts with both players receiving two cards. Only one of your cards is visible to your opponent. You calculate your score by adding both card values, which range from 1 to 11. Keep in mind, the opponent’s total stays hidden until the showdown phase.
Before the first card is drawn, you must place a bet. This doesn’t involve Robux or real money. Instead, it determines how far the buzzsaw will move depending on the round’s outcome. If you’re unsure about your hand, bet low. If you’re confident or holding a Trump card that can save you, go higher.
Each turn, you can:
- Draw a card (if you’re below 21),
- Keep your current hand,
- Or use a Trump card.
Modes And Controls in Twenty One
Drawing and staying both use up your turn. Trump cards don’t. You can use them before or after making a decision, which opens up key opportunities for strategic plays. But be quick because if you take too long, your turn will automatically be skipped.

Trump cards are randomly assigned at the start of each round. They can increase your total, subtract from the opponent’s score, or apply other effects. Use them wisely, especially when your total sits in the risky 14 to 17 range.
The round ends with the Showdown phase. At this point, the opponent’s second card is revealed, and the scores are compared. The player closest to 21 without going over wins the round. The saw then moves in favor of the winner.
Gameplay continues in this turn-based fashion until one player loses too many times. At that point, the buzzsaw makes contact and ends the match.
You can play in two modes:
- Multiplayer rooms against real opponents
- Closed rooms against AI bots
Controls are simple:
- Double-tap Left Mouse Button to draw
- Double-tap Right Mouse Button to stay
- Press Spacebar to activate a Trump card
There’s also an in-game shop, where you can buy different card packs using in-game Cash or Robux. These packs don’t change gameplay, only the visuals.
Twenty One is straightforward to learn but difficult to master. Understanding when to draw, stay, or use Trump cards makes the difference between victory and decapitation.
