Play money only, stored only in your browser
Every score on this page is play money from our simulators. The demo board is illustrative and generated from today's date, not a feed of real players. Your own best runs live only in your browser's local storage — they are never sent to us or to anyone else, and clearing your browser data removes them permanently.
The leaderboard
This casino simulator leaderboard pairs a deterministic, illustrative demo board with a personal best-runs section built entirely from play-money results your own browser has recorded — no account, no server-side data, no real money involved at any point.
Today's demo board
Illustrative rows, regenerated from today's date. Not real players, not real money.

What is real here, and what isn't
The top table on this page is a demo board, and we want to be completely plain about that rather than let it masquerade as live activity. It is generated from today's date using a simple, repeatable formula, so it looks the same to everyone who visits on the same day and changes again tomorrow. The masked names — things like j***n — mimic how a real leaderboard often displays partial usernames for privacy, but there is no real person behind any row here.
The bottom table, your best runs, is different in kind, not just in framing. It reads directly from a small piece of data your own browser has stored after you played our roulette, blackjack, baccarat or slot machine simulator. It is genuinely yours, genuinely local, and genuinely play money — never real, never shared.
Your best runs
Each of our four newest simulators saves your best play-money bankroll from that game to your browser's local storage the moment you beat your previous best. This page simply reads that same storage and lays it out as a small personal table: which game, what your best bankroll reached, and the date it happened. If you haven't played one of those simulators yet in this browser, that row simply won't appear until you do.
Nothing here travels between devices or browsers
Because the data lives in one browser's local storage, your best roulette run on your laptop will not appear if you open this page on your phone, and switching browsers on the same computer starts you with an empty table again. That is a deliberate trade-off for keeping everything here fully local and account-free.
How your data is stored, and how to clear it
The four simulators write a small JSON object to a single browser storage key, recording the game name, your best bankroll and the date it was reached, and updating it only when a new run beats the old one. This page reads that same key back out — nothing is sent over the network in either direction, and no cookie, tracker or account is involved.
Click “Clear my saved runs” above and the stored data is deleted immediately from this browser. The same result happens automatically if you clear your browser's site data, use a private or incognito window, or switch to a different browser entirely.
Why we built it this way
A leaderboard adds a small, honest incentive to actually play through a simulator's batch mode a few times rather than reading about the maths and moving on — and doing that without an account, a server or any real data collection kept the tool consistent with everything else on this site: play money, transparent mechanics, and nothing pretending to be more than it is.
If you're new to why these tools exist at all, our simulators hub explains what a casino simulator can and can't teach you, and our house edge explainer covers the maths every one of these games is built on.
Frequently asked questions
Is this leaderboard connected to real money or a real account?
No. Every number on this page — the demo board and your own best runs — is play money from our simulators. Nothing here is a real balance, a real prize or a real ranking against other people's real money.
Where is my best-run data actually stored?
Only in your own browser, in a feature called localStorage. It is not sent to any server, not visible to anyone else, and not tied to an account of any kind. Clear your browser data or click the clear button on this page and it's gone for good.
Why do the demo board's names look masked, like 'j***n'?
Because the demo board is not real players — it's a deterministic, illustrative set of rows generated from today's date, styled the way a real leaderboard displays partial usernames for privacy. It exists to show the layout, not to represent real activity.
Why does the demo board change from day to day?
It's seeded from the current date, so the same day always produces the same rows, but a new day produces a new set. That keeps the page from being a static, obviously fake screenshot while being completely transparent that nothing is live or real-time.
Which simulators feed my 'best runs' section?
Our roulette, blackjack, baccarat and slot machine simulators each save your best play-money bankroll from that game to the same browser storage this page reads.
