    • Betting Bankroll Planner – How Does It Work?

      Oddsmart’s Betting Bankroll Planner helps you choose the right staking strategy—flat, Kelly or Martingale—to meet your matched-betting wagering requirements while managing risk.

      Why It Matters
      Picking arbitrary stakes can blow your bankroll or leave bonuses uncleared. Our Tester models three core plans side-by-side so you can compare speed, volatility and ruin probability.

      Strategies Compared

      • Flat: Bet the same amount every time. Simple and low-volatility, but may clear turnover slowly.

      • Kelly: Stake a fraction of your bankroll proportional to your edge (win probability × (odds–1) – loss probability). Maximises growth and minimises ruin if your win-rate estimate is accurate.

      • Martingale: Double your stake after each loss until a win recoups losses plus base profit. Fast in theory but exposes you to huge drawdowns and bust risk.

      How It Works

      1. Inputs: Bankroll, turnover requirement, flat stake, Kelly odds & win rate, Martingale base stake, levels & win rate.

      2. Outputs: For each plan—bets or cycles to clear, turnover per cycle, total bets, bust probability, max exposure and required stake sizes.

      Real-World Example
      With £1,000 bankroll, £2,000 turnover, 2.0 odds and 47% win rate:

      • Flat at £10 needs 200 bets.

      • Kelly at £130 needs ~15 bets.

      • Martingale with five levels needs ~1,224 bets and carries a ~3% bust chance.

      By instantly quantifying trade-offs, Oddsmart’s Tester lets you pick the strategy that clears your bonus efficiently—without risking your balance.

    • Blackjack Calculator – How Does It Work?

      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

      • Custom Rules: Toggle surrender availability and soft-17 behaviour.

      • 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.

      • Integrated Glossary: On-screen explanations of each action.

      How to Use

      1. Set Rules: Match the casino’s soft-17 and surrender options.

      2. Enter Cards: Click your cards and the dealer’s up-card.

      3. Follow the Advice: The tool highlights the optimal move in real-time.

      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.

    • Casino Simulator – How Does It Work?

      Oddsmart’s Casino Simulator - our Deposit Bonus EV & Wagering Simulator is a free online tool designed to reveal the true value and time cost of casino matched-betting offers.

      It computes both the expected value (EV) and hours required to clear any deposit bonus by combining your inputs—deposit amount, match percentage, wagering multiplier, average stake, bets per hour—and your chosen game mix (slots, table games, live casino) with their respective RTPs.

      Under the hood, it calculates total bonus credits, total turnover required, time to clear (turnover ÷ stake × bets per hour), weighted RTP (sum of each game’s weighting × RTP), expected return (bonus × weighted RTP) and net EV (expected return – deposit).

      Our step-by-step guide shows you where to enter each parameter in the simulator’s spreadsheet, while a plain-English breakdown of the formulas demystifies the maths.

      In practice, you can plug in real-world examples—say, a £100 deposit with a 100% match, 30× wagering and a 50/30/20 split across slots, tables and live—and instantly see that although the bonus seems attractive, you’d need 60 hours to clear it for a net loss of £2.85.

      By comparing net EV per hour, you can prioritise high-value, fast-clearing offers and avoid time-draining traps.

      Beyond the basics, Oddsmart offers advanced tips—batch comparisons, bankroll allocation, refining weightings and tracking actual vs. predicted returns—as well as FAQs on accuracy, single-game play, exchange requirements and more, making the simulator a go-to companion for both newcomers and seasoned bonus hunters.

    • Progressive Jackpot Simulator – How Does It Work?

      Oddsmart’s Progressive Jackpot Simulator is a lightweight, spreadsheet-based tool that turns the glamour of growing jackpot pools into hard numbers.

      By entering five simple inputs—your bet size, the slot’s base RTP, the current jackpot amount, the jackpot-hit probability (e.g. 1/1,000,000), and your average spin time—the simulator instantly calculates:

      • Base EV per Spin (stake × base RTP)

      • Jackpot EV per Spin (jackpot size × hit probability)

      • Total EV per Spin (sum of base and jackpot EV)

      • Spins per Hour (3600 ÷ spin time)

      • EV per Hour (total EV per spin × spins per hour)

      • Expected Spins to Hit (1 ÷ hit probability)

      • Expected Time to Hit (expected spins × spin time ÷ 3600)

      These outputs show both your average profit or loss per wager and how long you’d likely play before hitting the big prize. A real-world example—£1 bets on a 95% RTP slot with a £200,000 jackpot at 1-in-2,000,000 odds and 4-second spins—reveals a nominal EV per spin of £1.05 but an expected 2,222 hours (93 days) to win.

      This stark contrast highlights how even “positive” EV can mask impractical waiting times.

      Whether you’re chasing life-changing payouts or seeking steadier matched-betting returns, this simulator equips you with the EV-versus-effort metrics needed to decide if a progressive jackpot is worth the marathon.

    • Slots Game EV Calculator – How Does It Work?

      Oddsmart’s Slots Game Expected Value (EV) Calculator is a lightweight online tool that translates any free-spin or bonus-credit promotion into a clear profit forecast.

      By entering just four inputs—bonus-credit value, number of free spins, spin value, and the game’s RTP—you instantly get three outputs: EV from bonus credits, EV from free spins, and total EV in pounds.

      Expected Value (EV) measures your average long-run return by weighting each possible outcome by its probability.

      For bonus credits, EV is simply bonus × (RTP ÷ 100).

      Free-spin EV subtracts the total stake (spins × spin value) from the theoretical return (stake × RTP ÷ 100).

      Summing these gives your overall expected gain or loss.

      With this calculator you can rapidly compare bookmakers’ offers, prioritise the highest-EV promotions, and allocate your bankroll where it earns the most.

      A positive total EV signals a profitable opportunity; a negative one warns you to skip or renegotiate terms.

      An example with £10 credits and 10 spins at 10 pence each on a 10% RTP shows a net EV of –£89, demonstrating how seemingly generous freebies can be money pits once the maths is laid bare.

      Beyond raw numbers, Oddsmart’s guide explains the underlying formulas, offers practical examples, and suggests advanced tips—like logging cumulative EV and balancing time-vs-value—to help matched bettors turn promotional complexity into disciplined, data-driven profits.

    • Slots Spin Calculator – How Does It Work?

      Oddsmart’s Slots Spin Calculator is a no-frills free online tool that forecasts your average return after a set number of spins on any slot machine.

      By entering just three inputs—your stake per spin, the number of spins, and the slot’s published RTP—the calculator multiplies these values to reveal your Expected Balance, the long-run average you can expect to walk away with.

      This clarity helps you make data-driven decisions: whether you’re burning through free spins from matched-betting offers or funding paid sessions, you’ll know in advance if the promotion or game is worth your time and bankroll.

      For example, 30 free spins at £0.20 on a 95.97% RTP slot yield an Expected Balance of about £5.76, so if winnings are capped at £5 you’d see a shortfall versus theoretical value.

      Beyond simple forecasts, the tool supports smarter session planning and bankroll management: set realistic win-loss limits, compare low-RTP titles, and optimise session lengths for best ROI.

      Advanced tips cover segmenting your slots fund, comparing RTPs across games, and integrating wagering requirements for true net value.

      Whether you’re chasing small promotional margins or just want to avoid tilt, the Slots Spin Calculator equips you with the hard numbers you need to spin confidently—and stop before the odds stop you.

    • Wagering Calculator – How Does It Work?

      Oddsmart’s Wagering Requirement Calculator cuts through casino bonus jargon to reveal how much a deposit match is genuinely worth after you satisfy its turnover conditions.

      By entering your deposit amount, match percentage, and the wagering multiplier (e.g. 30×), the calculator computes:

      1. Total Bonus: your deposit × match %.

      2. Expected Monetary Value (EMV): total bonus ÷ wagering requirement.

      3. EMV as % of Deposit: EMV ÷ deposit × 100.

      This simple formula shows that a “100% match up to £200” with a 30× requirement is really only worth £6.67 (3.3% of your £200 deposit), rather than the full £200 headline.

      A lower wagering multiple, like 10× on a 50% match, delivers a far stronger EMV (e.g. £5 on £100 deposit = 5%).

      With clear EMV figures, you can compare offers side-by-side, prioritise bonuses that boost your bankroll, and avoid spending hours on turnover traps that yield negligible returns.

      Advanced tips include targeting sub-10× requirements, clearing with high-RTP games to minimise house edge, and weighing EMV against time-to-clear to optimise your matched-betting ROI.

      Whether you’re chasing your first bonus or juggling dozens, the Wagering Requirement Calculator empowers you to turn complex casino terms into straightforward, data-driven decisions—so you focus only on the offers that truly pay.
