AskSpinner Casino Tools

Choose the right casino tool

Casino tools help you work through the numbers and information behind an offer or a game. A wagering calculator turns bonus conditions into a playthrough total. A simulator shows how a virtual balance changes over a session. A licence checker helps you find information about a casino’s operator.

Our free online calculators and simulators run in your browser, with no account or deposit needed. Start with the question you want to answer: how much must be wagered, how a game’s settings affect a session, or which licence records to check. The country sections link to tools built for local records.

Calculate bonus wagering requirements

The Bonus Wagering Calculator helps you read a casino bonus in terms of the total qualifying stakes it requires. It supports deposit bonuses, fixed bonuses and free-spin winnings. For a deposit bonus, select whether the multiplier applies to your deposit, the bonus or both.

For example, a deposit of 100 credits with a 100% bonus gives a combined amount of 200 credits. A 30× requirement on deposit plus bonus creates a wagering target of 6,000 credits. If the requirement applies only to the bonus, the target is 3,000 credits.

Game contribution matters too. In deposit and fixed-bonus modes, a 50% contribution means only half of each stake counts: a 6,000-credit target needs 12,000 credits in stakes. Free-spins mode calculates wagering on the winnings entered; check any game-contribution conditions separately. These totals describe required playthrough, not the money you are guaranteed to lose or withdraw.

Read the result alongside the offer’s expiry date, eligible games, maximum stake and withdrawal conditions. Enter every amount in the same currency; changing the display unit does not convert the figures.

Try the roulette simulator

Use the Roulette Simulator to place virtual chips, choose a wheel and review a session’s spin history. European, American and triple-zero versions are available. The balance chart shows the effect of the selected bets across the completed spins.

To explore the differences, keep the starting credits and bets consistent while changing one setting. You can also repeat the same setup to see how random results vary. A session ends early if the remaining balance cannot cover the full bet, so check the number of completed spins before comparing runs.

Explore slot RTP and volatility

The Slot Betting Simulator is a slot machine simulator for exploring starting credits, stake size, session length, return to player (RTP) and volatility. It shows the balance history, total stakes, returns and largest drawdown in a simulated session.

RTP describes a long-run average, while observed RTP measures the returns divided by stakes in the run you just completed. A short session can differ substantially from the selected percentage. The Gambling Commission’s explanation of return to player describes why an RTP percentage is not a promised return for an individual session.

Volatility changes the frequency and size of returns in our model. Try changing it while leaving the other settings alone, then inspect the session details. This simulator uses a simplified payout model; it does not reproduce the reels, bonus features or results of a particular commercial slot.

Compare poker hands and ranges

The Poker Odds Calculator compares Texas Hold’em hands for two to nine players. Choose exact cards, a starting-hand range or a random hand, then add any known community cards and dead cards.

Win percentage counts outright wins. Equity also includes your share of tied pots. The calculator labels exact enumeration and simulation estimates separately; neither result accounts for future betting or tells you what the next card will be.

Practise blackjack decisions

Blackjack Simulator — Play against the dealer with virtual credits. Practise hit, stand, double and split decisions, then check each hand’s return. The table shows its six-deck, soft-17 and 3:2 blackjack rules before you deal.

Explore Aviator multipliers

Aviator Simulator — Follow an Aviator-style flight and cash out before the multiplier crashes. Compare manual cashout with a preset target using virtual credits. This independent practice model does not reproduce or predict the official game.

Explore Plinko payouts and probabilities

Plinko Simulator — Drop balls through a peg board with virtual credits. Compare 8, 12 and 16 rows, change the risk level and inspect the payout table. Each ball follows a fresh random path; risk changes the payouts rather than the chance of landing in each slot.

Explore Mines probabilities

Mines Simulator — Choose how many mines are hidden on a 25-tile board, reveal tiles and decide when to cash out. Compare the chance of the next safe pick with the available return. This is an independent practice model with its own payout rules; it does not reveal the mines in another game.

Convert betting odds and probability

Odds Converter — Convert decimal, fractional and American odds into equivalent formats and implied probability. Add a stake to separate the total return from the potential profit. For example, decimal odds of 2.50 equal fractional odds of 3/2, American odds of +150 and an implied probability of 40%.

Practise baccarat rules

Baccarat Simulator — Practise choosing Player, Banker or Tie, then watch the hands settle under standard drawing rules. The table pays Banker wins at 0.95 to 1, Player wins at 1 to 1 and Tie wins at 8 to 1. A tie returns Player and Banker stakes. All stakes and returns are virtual credits.

Calculate a parlay return

Parlay Calculator — Combine the odds of several selections, enter a stake and separate the potential total return from profit. Mark selections as won, lost or void to see how settlement changes an accumulator. This calculator uses the prices you enter; it does not quote a bookmaker’s same-game parlay.

Explore Dice win chances

Dice Simulator — Choose a roll-under or roll-over target and compare the win chance with its payout multiplier. Use virtual credits for individual rolls or a fixed batch, then review the session results. This casino-style Dice model uses numbers from 0.00 to 99.99, rather than a six-sided die.

Check casino licence information

For a Philippine casino, start with the PAGCOR License Checker. Keep the website address and operator name together when reviewing a result, and check the source records and their update date. A familiar brand name alone does not identify the exact website you are visiting.

Country tools stay with the markets whose records they use. The Philippines checker is available through its country site. Brazil’s tools and Mexico’s planned SEGOB License Checker are marked Coming soon; they are not available to use yet.
