Roobet Blackjack Original: seed-shuffled single-player table

01Rules of the table

The Original follows the standard blackjack frame: the player and the dealer each receive cards, the aim is a hand value closer to 21 than the dealer's without going over, and a two-card 21 is a blackjack. After the deal the player chooses between hit, stand, double and, with a pair, split; the dealer then draws according to the table rules shown in the game. Because the deck order is produced from the seeds before the first card is dealt, the sequence of cards is fixed for the round and the player's actions only decide which of those cards are taken.

Specific table rules such as the number of decks, the dealer's action on a soft 17, the payout for a blackjack and the available side bets are printed in the game's rules panel. The operator's policy pages do not reproduce them, and this guide gives no figures it cannot source. The game runs against the house without a live dealer, in Fun Play as well as for real money.

• standard aim: closer to 21 than the dealer without busting;
• actions: hit, stand, double, split on a pair;
• the deck order comes from the seeds, the actions from the player;
• table rules and side options are printed in the game's rules panel;
• single player versus the house, no dealer stream.

The Roobet guide opens with an overview of the catalogue, the cashier, the rewards and the licence; this chapter goes into one part of it in detail.

02Playing a hand

The table shows a chip selector, the bet area and the action buttons. A balance on the crypto side of the wallet is required for real hands; Fun Play needs no deposit. The table is open to adults only; limits for deposits, losses and wagers are described on the responsible gambling page.

1. Open Blackjack in the Roobet Originals category.
2. Set the stake with the chips, from $0.01 to $20,000, and press Deal.
3. Read the two cards and the dealer's visible card.
4. Choose hit, stand, double or split; repeat until the hand stands or busts.
5. Let the dealer draw and read the result.
6. Open the hand in the history to copy the seeds, the nonce and the actions hash.

Each action taken in a hand is serialised in order and hashed; the actions hash is shown in the bet details.

03Limits for the Blackjack Original

The Game Policy v4.5.0 gives no special figure for the Blackjack Original, so the standard Originals limits apply. A double or a split increases the amount at stake within the same hand; the maximum win cap applies to the payout of the bet.

The rewards chapter explains how Originals wagers feed rakeback; the Originals hub lists all limits side by side.

04Provably fair: four ingredients with an actions hash

The fairness page lists four ingredients for the Blackjack Original. The server seed comes from the casino. The client seed also comes from the casino in this game: it is the hash of a randomly generated alphanumeric sequence created per game, not a value set by the player. The game nonce rises by one after each bet. The fourth ingredient is the actions hash, a hash of the game actions serialised in chronological order, provided by the casino. At the start the player receives a unique SHA256 hash of the server seed, which stays unchanged until the seed is revealed or changed.

On verification the casino reveals the server seed, re-runs the server seed, the client seed and the nonce to regenerate the shuffling hash of the hand, and resets the nonce and the seed. The player can hash the revealed seed and compare it with the hash shown at the start; the Verify Results button on the Blackjack tab of roobet.com/fair runs the same shuffle logic. The actions hash proves that the recorded sequence of hits, stands, doubles and splits is the one the player took. The chapter on fairness and licensing explains the method in general.

05Mistakes at the Blackjack Original

Players who switch from live tables tend to expect the same table rules and a player-set client seed. The table lists these and the panel slips.
