Game contribution and qualifying turnover
Learn how contribution percentages affect promotional turnover, why they differ from RTP and how to investigate a progress-counter mismatch.
Read the guideDeposit-match percentages and caps
Calculate a percentage match and its ceiling, separate your deposit from the reward and avoid treating the advertised cap as a spending target.
Read the guideTurnover, deposits and loss are different numbers
Follow a simple account ledger to distinguish deposits, accumulated stakes, returns and net loss without mistaking a progress bar for cash.
Read the guideRTP and house edge without session promises
Understand theoretical RTP and house edge, reproduce a model calculation and see why averages cannot predict a session or bonus conversion.
Read the guideVolatility explains uncertainty, not an advantage
Explore why equal theoretical returns can produce different short-run balances and why volatility labels do not establish a winning advantage.
Read the guideWhat a bonus calculator can and cannot tell you
Audit a bonus calculator inputs, units and formulas, and distinguish fixed arithmetic from uncertain forecasts about costs or future balances.
Read the guidePercentages, multipliers and percentage points
Decode match percentages, contribution rates and wagering multipliers with examples showing why the base matters as much as the headline number.
Read the guideNominal spin value versus cash value
Calculate nominal spin stakes without calling them cash, savings or guaranteed returns, and compare the conditions that the multiplication omits.
Read the guideA worked cashback calculation with clear assumptions
Work through an eligible-loss base, percentage, cap and rounding rule, then distinguish a cash rebate from conditional promotional credit.
