Everything runs in your browser — no sign-up, no tracking of your inputs, and no rounding in the house's favour.
Every casino front page is a sales page. It tells you the maximum multiplier, the headline bonus figure and the shiniest VIP tier — and quietly leaves out the probability of hitting the multiplier, the wagering cost of clearing the bonus, and the turnover the tier actually requires. These six calculators fill in the missing column. They are built on the same formulas the casinos themselves use, which is exactly why the results are often unflattering.
The Mines calculator gives you the exact multiplier and the exact win chance for every combination of mines and gems on the standard 5×5 grid, so you can see precisely where the 1% house edge is hiding. The bonus wager calculator converts any "100% up to $1,000" headline into required turnover, expected clearing cost and a plain verdict: take it or decline it. Most bonuses with 40x wagering fail that test, and the calculator will say so.
The rakeback calculator shows what a rebate really returns at your turnover — rakeback is a refund on losses, never a profit engine, and the tool makes the distinction impossible to miss. The VIP calculator prices a typical crypto-casino ladder in the only currency that matters: dollars wagered and weeks of your life. The session cost calculator turns house edge, bet size and pace into a cost per hour you can compare against any other form of entertainment. And the bankroll calculator runs the classic gambler's-ruin formula to show how likely a bankroll really is to reach a target before it dies.
None of these tools require an account and none of them connect to any casino. They are mathematics, not advice — but if the mathematics keeps telling you an offer is bad, that is worth listening to. If you do play for real, do it with money you can afford to lose, and read our responsible gambling page first.
Frequently Asked Questions
Are these calculators accurate for real casinos?
Yes, within their stated assumptions. Each tool uses the standard published formulas — hypergeometric odds for Mines, expected value for bonuses and rakeback, and the gambler's-ruin formula for bankroll survival. Where an input varies between casinos (house edge, wagering multiplier, rakeback rate), you set it yourself, so the result matches the specific offer you type in.
Do the calculators send my numbers anywhere?
No. Every calculation runs as JavaScript in your own browser. Nothing you type is transmitted, stored or logged — reload the page and it is gone.
Why do the results so often say an offer is bad?
Because most offers are. Casinos are businesses built on a house edge, and promotions are priced so that the average player still loses. When a bonus or rakeback deal genuinely has positive value at your inputs, the calculators will show it in green — it just does not happen very often.
Can a calculator help me win?
No calculator changes the house edge. What these tools do is stop you overpaying: they identify expensive games, bad bonuses and unrealistic VIP chases before you commit money. Knowing the real cost is the closest thing to an edge a player can get.
Why Take a Code From Here
Most code pages are written once and abandoned. Ours is maintained, priced and dated — here is what that means in practice.
Everyday checking
Every code is re-tested against a live registration form rather than copied from another aggregator. When an offer moves, the page moves with it.
0days of continuous trackingActual bonuses, not expired ones
Dead codes get removed, not left up to collect clicks. Each card carries the date it was last confirmed working, so you can judge how fresh it is instead of trusting us.

These are negotiated exclusives, not the default offers on the operators’ own front pages. Where a public offer is genuinely better, we say so instead of hiding it.

Every offer is run through our own wagering maths, and several of our calculators will tell you an offer is not worth taking. A coupon site that never says no is selling, not advising.
