Explorables: feel the maths, don’t just read it
Interactive tools that let you run the numbers yourself. Each targets a common myth about gambling — and none is a “winning strategy”. The edge is always there; that’s the point.

The house edge, over a session
Start with $200 and bet $1 a spin. Watch the balance wander — then see where the maths takes it.
Live · house-edge simulator
Predict first: after 200 spins of $1 at 96% RTP, your $200 will be…
Myth it busts: “96% RTP means I can’t really lose.” Same RTP, higher volatility — it still drains over time.
Interactive model§02
Is red “due”?
Bet that a streak breaks — or that it continues — and track how often “due” actually wins.
Live · gambler’s-fallacy demo
Predict first: betting on the “due” colour, what win rate do you expect?
Myth it busts: The gambler’s fallacy — that past results change the next independent spin. They don’t.
Interactive model§03
Do the odds add up?
Adjust the prices in a match-odds market and watch the implied chances total more than 100%.
Live · odds & overround explorer
Predict first: for a fair 3-way market, the implied chances should add up to…
Myth it busts: “These odds are generous.” The implied chances always sum past 100% — that overround is the bookmaker’s margin.
Interactive model§04
Is a bonus free money?
Set a deposit, bonus and wagering requirement, and see what it really costs to cash out.

To turn a $100 bonus into withdrawable cash you must bet $3,500 at 96% RTP — the house expects to keep $140 of it along the way. “Free” bonuses are marketing; the wagering requirement is where the edge lives. Excludes max-cashout caps and variance.
Myth it busts: “$100 free.” The wagering requirement is where the house edge quietly takes it back.
