Controls and play

Choose HIT, STAND, or DOUBLE with A/D and confirm with RETURN. HIT draws one card. STAND resolves the hand. DOUBLE raises your stake to 4, draws exactly one card, and resolves immediately. DOUBLE is available only with the original two cards and at least 4 chips.

Directions work on the keyboard or pad; the pad button also acts as RETURN. SPACE opens confirmation to restart this stage. NO is selected initially. Choose with A/D, confirm with RETURN, or cancel with SPACE. Play pauses during confirmation. CTRL+C returns to BASIC.

Ranks, face cards, and suits appear within individual frames, and the hidden card has a distinct back. Dealing, dealer draws, results, and chip changes appear in order, with time to inspect each hand. Wait for animations to finish before pressing again.

An ace counts as 1 or 11; face cards count as 10. The normal stake is 2. A winning 21 on the first two cards earns 3. The dealer draws until reaching 17. A tie leaves your chips unchanged. The dealer's second card stays hidden until resolution. Having fewer than 2 chips ends the game.

操作と遊び方

A/DでHIT・STAND・DOUBLEを選び、RETURNで決定。HITは1枚引き、STANDは勝負、DOUBLEは賭け金を4にして1枚だけ引き勝負します。DOUBLEは最初の2枚かつ持ち金4以上で選べます。

方向キーはキーボードまたはパッド、RETURNはパッドのボタンでも操作できます。SPACEでこの面のやり直し確認を開きます。やり直し確認はNOが初期選択です。A/Dで選び、RETURNで確定、SPACEで取り消します。確認中は進行を止めます。CTRL+CでBASICへ戻ります。

カードの枠内に数字・絵札とスートを並べ、伏せ札を区別します。配る途中の移動、相手の追加ドロー、勝敗と持ち金の増減を順番に見せ、各勝負の確認時間を設けます。演出が終わってから次のキーを押してください。

Aは1または11、絵札は10です。通常の賭け金は2、最初の2枚で21なら勝利時に3増えます。相手は17まで引きます。引き分けは持ち金が変わりません。相手の2枚目は勝負まで伏せられ、持ち金2未満で終了です。
