Oddsmart’s Blackjack Calculator is an interactive calculator that delivers the mathematically optimal play—hit, stand, double, split or surrender—for any hand against the dealer’s up-card.
Built on Monte Carlo simulations and standard “basic strategy” matrices, it adapts instantly to your chosen rules (dealer hits or stands on soft 17; late surrender on or off) and distinguishes hard totals, soft totals and pairs.
Core Features

Hand-Specific Guidance: Colour-coded recommendations for every situation.
Mobile-First Design: Responsive interface for quick taps in live play.
Practice Mode & Reporting: Drill simulated hands, track correct vs. incorrect decisions, and review session stats.

Why It Stands Out
By automating complex lookups and tailoring advice to exact rules, it removes guesswork and accelerates decision-making—minimising the house edge to around 0.5%.
Whether you’re a beginner memorizing basic strategy or a veteran refining your edge, Oddsmart’s tool combines dynamic recommendations, rule accuracy and performance tracking to help you play every hand with confidence and precision.
