Each month you bring the same amount of money and bet a fixed stake, one bet at a time, at the real odds of the game you pick. The month ends when the money runs out, when you reach your walk-away target, or after 10,000 bets. Whatever is left goes into a savings account. This runs for 1,000 simulated gamblers over the whole period, and the results show the typical one and the luckiest one in ten.
It is the share of every bet a game pays back on average. A slot machine at 94% pays back $94 for every $100 bet and keeps $6. That edge is small on one bet, but the same money gets bet again and again, so the edge is paid many times over each month.
No. A walk-away target changes how often a month ends ahead, but not the edge on each bet. Across many months the losing months outweigh the winning ones. A higher target, or none at all, keeps the money in play for longer and usually makes the result worse.
The same money goes in at the end of each month and grows at the rates you enter, treated as yearly rates. The rates stay the same every year. Real returns rise and fall, and investments can lose value, so treat the investing line as an estimate, not a promise.
Each game uses a simplified payout table whose return to player matches common published figures: slot machines 94%, single-zero roulette 97.3%, double-zero roulette 94.7%, sports betting at standard odds 95.5%, blackjack with perfect strategy 99.5%, and lotteries and scratch cards 50%. Real games vary by venue and machine, and most blackjack players do worse than perfect strategy.
