How to Play

Spreadsheet Blackjack uses standard blackjack rules. The goal is to have a hand total closer to 21 than the dealer without going over.

Card Values

• Number cards (2–10) are worth their face value.
• Face cards (J, Q, K) are worth 10.
• Aces are worth 11 or 1, whichever is more favorable.

Game Flow

1. Set your bet using the adjustment buttons (j/k) or by clicking the values on row 9.
2. Press Deal (n or Space) to receive your cards.
3. Choose an action: Hit, Stand, Double, or Split.
4. The dealer reveals their hand and draws to 17 or higher.
5. Winners are paid, losers are collected, and a new round begins.

Actions

• Hit (a or Space) — Take another card.
• Stand (s or Enter) — Keep your current hand.
• Double (d) — Double your bet and receive exactly one more card.
• Split (p) — If your first two cards are of equal value, split them into two separate hands. You may split up to 3 times (4 hands max). Aces get one card each and automatically stand.

Dealer Rules

• Dealer hits on soft 17.
• Dealer stands on 17 or higher (hard or soft 18+).
• Dealer does not check for blackjack until after all player actions are complete (European no-peek rule).

Payouts

• Blackjack: 3:2 (natural 21 on first two cards).
• Win: 1:1 (even money).
• Push: Bet returned, no win or loss.
• Loss: Bet is forfeited.
