About
BlackjackSprint21
A single-player card game where speed, strategy, and nerve determine your score. How close can you get?
Draw cards to reach as close to 21 as possible without going over. Each level has a minimum threshold you must reach to advance. Tap HIT to draw a card, STAND to end your turn.
Level Score = (Hand Total − Threshold + 1) × 80
Your level score is multiplied by your current streak for the total contribution.
Perfect 21 (Blackjack) awards a flat +500 bonus on top of your level score.
Levels 1–3: reach ≥ 14
Levels 4–6: reach ≥ 15
Levels 7–9: reach ≥ 16
